Key points to put on a Spec sheet

If you’re new to this blog, or lingerie design itself, you may wonder what a specification sheet is or if you need one for your lingerie designs. And whilst I have written about “how to spec a bra and brief” and drafted out templates so you can draft your own ones out, if you haven’t seen these , or want to know how important a spec sheet is then you need to know the following.

A specification sheet is a detailed sheet, with all the important measurements of your garment with it’s base size and all the other sizes you wish to produce. As well as standard information like your company name and style number/name of your garment, it will have a technical drawing with reference points to garment.

For example if you were to spec up a brief, you would have the measurement of the medium waist say for example 30cm then you would list the waist measurement of all the other sizes. So small would be 27.5cm and large would be 32.5cm (going on the grade of 2.5cm on the half).

If you need your lingerie graded, some graders won’t need a a spec sheet to work from and will just apply standard grades, and can produce the spec sheet for you .

It’s a bit like the chicken and egg, in which comes first, the grade or the spec. To write a spec sheet, you need to know how much everything grades by, but to get your lingerie graded you need to take the information off the spec sheet.

Some graders will be able to do your spec sheet for you, but some will want to work off your spec sheet. So it’s a balance of finding what works well for you.

When it comes to briefs I usually start with approximately eleven measurements :

And after that it would be extra measurements if you have more detail or seams on the brief, for example if you’ve a brief with a top part of fabric and a lower part then you would need both these measurements.

On a bra I usually have the minimum of twenty measurements, but depending on the bra style only 15+ may get used, These include, top of cup, through the cup - going through the fullest part of the bust, the length of the wing - relaxed and stretched. For a more detailed list of all the measurements, they are listed in the book “How to spec a bra and brief”

Not only do pattern makers and graders follow your spec, so do quality controllers, when you receive your sample or your range back from the lingerie manufacturers, the lingerie spec will be what you measure your lingerie by, ensuring all the lingerie manufactured are within tolerance (a measuring discrepancy given to all make-up of garments) before they can be sold.

WHAT TO PUT ON THE SPEC SHEET

So the key points to put on your lingerie spec sheet, are the following:

  1. Company name

  2. Style number or name

  3. Garment description

  4. Date

  5. Technical drawing of your lingerie including references and arrows)

  6. POM (Point Of Measurement correlating to your reference points)

  7. Sizes

  8. Tolerance each POM has

There are many different layouts of spec sheets, I tend to stick with my tried and tested spec sheet, which lay out has been used by factories. If you are wanting just a layout of a spec sheet to use, then your get the design sheet of the spec sheet here.

How to Tech, Spec and Grade a bra and brief

It’s finally here !!

*The book How to tech, spec & grade a bra and brief is available to pre-order with a 20% discount. And will be shipped out by 14th February.

Back in 2013 I started to write the technical book and all the aspects of getting your lingerie designed the technical way, with tech packs, spec sheets and grading your lingerie. With understanding and being able to write and read a specification sheet, writing a tech pack and learning and being able to grade a bra and brief, being the main important aspects as I realised there wasn’t much out there at the time. I was eight months pregnant when I finished the first draft, and knew I had to release the book in three parts before being able to release it in one big book. This was so I could concentrate on the content and for it not to be rushed and for all angles to be covered.

Fast forward five years later (and weirdly being nearly eight months pregnant again) it has finally been all wrapped up into one book. So just to clarify this book contains “How to spec a bra and brief, How to write a bra and brief tech pack, and How to grade a bra and brief”.

I know when I finished university I didn’t really understand writing a spec sheet, was pretty clueless about fashion technical drawings, writing a tech pack, working as a garment technologist or pattern maker, or even liaising with lingerie manufacturers. I just knew how to design lingerie and make the basic patterns and knew a little about grading lingerie.

The vision from the start was to take three or four bra and brief styles and repeat them throughout each section. so you could follow how that style went through each process. Which lets me honest, the technical side of lingerie design can be tricky enough without trying to piece everything to together.

So this book will take your beautiful designs and get them moving a step further down the line of production, from idea to reality, and even if you plan to outsource everything, it’s always handy to know how it all works.
