We specialise in working with start-ups and can guide you through the overwhelming process of turning your designs into reality

As a start-up you have a lot of questions, almost all of them we get on a regular basis. So here are the answers…

What is the first step?

To create a fashion brand, there are a few things you should consider:

1.Develop a clear brand identity: This includes determining your brand’s aesthetic, target market, and mission.

2.Create a product line: Decide what types of clothing and accessories you want to sell and how you will source materials and manufacturing.

3.Build a website: This is where customers will go to learn about your brand and purchase your products. Make sure to include high-quality product photos and clear descriptions.

4.Marketing and promotion: Develop a plan for getting the word out about your brand, including social media marketing, email marketing, and influencer partnerships.

5.Finances: Determine your budget and create a financial plan to ensure your business is sustainable. This may include seeking funding from investors or applying for loans.

It’s also helpful to be familiar with the fashion industry and stay up-to-date on trends and changes. Networking and building relationships with others in the industry can also be beneficial.

Book a consultation with us if you require an in depth discussion about your idea.

How much is it going to cost?

This is the #1 question we get asked… and it is the most impossible one to answer. No two garments are the same, even a basic t-shirt! You have to consider which services you will need (pattern drafting to manufacturer), what sizes you will need, the type of fabric, how many details there are, and what trimmings you will need. The list goes on…

The best way to estimate costs is to send us your designs or design ideas to be able to give you an estimate.

When you send us your designs, Please list the services you need.

What are your MOQ (Minimum Order Quantities)?
We don’t have MOQ
How long will it take?
Again, depending on which services you need, it can take anywhere from 3 working days (for digitizing and grading) to a few months to achieve what you want (sample made in your chosen fabrics, trims and fit).
Can you talk me through your process?
Yes, we can! If you go back up to “services,” you will see everything we do in the natural flow of developing a fashion sample from start to finish. Please take your time to read through each stage.

You can book a consultation with us if you have more questions.

Can I come and visit the studio?
Yes, absolutely! You can see the studio as part of your consultation, which you can book online.

No, we do not give away our blocks. However, we can create personalized blocks for you with measurements to your specifications.
What type of digital files can you work with?
What type of digital files can you provide?
What is a 'toile'?
Great question! This is an industry-standard term to describe a ‘prototype’ or ‘test run’ of your garment.

It is usually made from calico, untreated cotton, which is super cost-effective. However, we advise you to use the same fabric or a similar fabric to the one you are going to use in your final sample. By using the same or a similar fabric, you will be able to see and feel the finished product, reducing the number of changes.

What is a 'sample'?
A sample is a final garment made up of your chosen fabrics and trims. This is what you will give to your manufacturer, so they have an example of the design of what they are making for you.
What is Pattern Grading?

Pattern grading is an essential part of the garment production process, as it allows companies to produce a range of sizes from a single base pattern. It involves making precise adjustments to the base pattern to create patterns in different sizes while maintaining the fit and style of the original design. There are several pattern grading methods, including manual grading, which involves making physical adjustments to the pattern using grading rulers and other tools, and digital grading, which involves using computer software to make the necessary adjustments.

We use anthropometric knowledge to grade your pattern to specific size ranges from a base size sample pattern. We can apply industry standard grading rules, follow your company’s established grading system, or assist you in creating your own bespoke grading specifications. Grade House will ensure that the grade rule used reflects the targeted market sector for which the product is intended. Considering the price point, material type, retail level, and demographic of the consumer, gender, age range, garment usage, and their preferences in style and vanity.

Market Specific Sizing

Our ethos is that one size will not fit all, and therefore no one sizing system will be suitable for all our clients. We believe the most successful route to market acquisition for clothing brands is to research and target a specific customer base in order to guarantee their satisfaction and, by extension, their repeat business. We invest time and our knowledge of 15 years in the industry to enable our clients to expand beyond standard grading rules and into a more profitable sizing system designed specifically for them and their target demographic. We can do this for young start-ups by discussing your researched consumer profile (gender, age range, garment usage, and their preferences in style and vanity) as well as for already established brands by analysing data on your current customer base. The main markets we currently consult are a range of High-End Luxury Designers to Start-up companies. However, we are confident we can tackle further niche markets, so feel free to book a consultation and challenge us to yours today.

Womenswear Grading

For ladieswear, when designing a bespoke grading rule system, the main aspects to take into account are the consumer profile (age range, garment usage and style preferences) and the place your brand sits in the current market. Selecting and manipulating the size range is also particularly important for graders of womenswear as it can dramatically affect the perception of the brand and, therefore, the number of sales. For example, selecting a size range that skews smaller or larger can be advantageous in different market sectors. Additionally, the trend for vanity sizing amongst competing brands can be particularly profitable if executed within a bespoke grading system.

Menswear Grading

For menswear, the sizes used are 34, 36, 38, 40, 42, 44… 60 or S, M, L to XXXL will be determined by the type of garment. The identity of the customer and where the brand is placed in the market are contributing factors in deciding the measurements used in the base size pattern. The two measurement graders pay particular attention to our stature (ratio between chest and waist) and height (short, regular or long). Another feature of menswear grading is the research that indicates that men are less likely to try on garments before purchasing them. Bespoke grading means that you can design increments to maximise your exposure across the sizing spectrum, and secondly, you could closely align yourself to the sizes used by your competitors so that your consumer will be able to successfully select a size that fits and therefore reduce your amount of returns.

Childrenswear Grading

For childrenswear, we recommend that age be used for sizing increments instead of height, as market research suggests that height is confusing for consumers. Childrenswear can either be graded as single sizes or dual sizes, and this will be determined by the type of garment and market sector. We will then consider which age group the range can be broken into, e.g. babywear (0-2), kidswear (3-11) or teen wear (12-16). As you cross over into an older sector, an additional base size pattern is recommended due to differences in growth between genders. Bespoke grading is commonly used in childrenswear as it is more location targeted than other market types, and garments will be sized differently in the UK compared to European or US standards. We would also like to take this chance to reinforce the importance of adhering to each country rules and regulations for components and fabrics when designing childrenswear. Further information on British garment manufacturing regulations can be obtained here.

Sportswear Grading

For sportswear, the base size pattern will already contain enough allowances to allow ease of movement during the activity the garment is used for. It is the type of activity and garment type that will impact the design of the grading system. The core consumers of each of these garments are different, and the fitted lycra top is more likely to be consumed by a person concerned with high-impact sports compared to a person who is new to sports and would be more likely to consume a regular t-shirt. Therefore you may consider sizing each of these slightly differently to meet the demands of each consumer. We would also recommend using a single-size system (e.g. 8, 10, 12, 14, 16) not only because the fitting would be more comfortable but also because this would allow a customer to move down the range as physical fitness increases. This would enable the customer to see a more encouraging change and make them more likely to complete the purchase compared to a dual-size system (e.g. S, M, L).

Plus Size Grading

The industry considers true plus size to be sizes above a UK size 18. One of the most important things we will consider for grading plus size is what type of body shape the clients will be, as there is much greater variety in plus size bodies. There are also many opportunities for expansion in this market sector as different lines can target more niche body shapes, such as tall plus-size garments. If you are planning to extend a previously established line above this threshold, we would recommend creating an additional base size pattern in order to account for the different allowances needed in various parts of the garment. For example, special attention needs to be paid to the measurements of the armhole, shoulder length, across back, bust waist and hips ratio. If you are starting a new line devoted just to plus size clothing and need advice on standard grade rules for plus size, we would recommend creating a base size pattern in sizes 18 or 22.

Maternity Grading

For maternity clothing, the sizing is typically arranged as a normal UK size, e.g. 6, 8, 10, 12, 14, 16 and then sometimes broken down further by trimester or month of pregnancy. The base pattern is typically aimed at a woman in the second to the third trimester, as normal clothing can fit some women for the first trimester. Trousers are sized using a waist size, e.g. 26, 28, 30, 32, and remain the same waist size as the woman would wear pre-pregnancy but account for extra growth in the stomach and additional areas in the base size pattern. Bespoke grading is specifically useful in this market as woman’s bodies can change in different parts during pregnancy, so targeting a specific niche could be particularly profitable if done successfully.
