Fashion Language 101:
Whether you're in the fashion industry yourself, know someone who is, or simply know nothing other than you need clothes to cover your body; you know that there's plenty of words that may seem foreign to you at first glance. If you related to any of that than you've come to the right place, because I'm here to help!
Here are a few words and their proper definition / my version of it. You might have seen these used throughout my site or perhaps someone else's.

Patterns are usually made of paper and are sometimes made of sturdier materials like paperboard or cardboard if they need to be more robust to withstand repeated use.
Lightweight cotton cloth in a plain weave. Prototype: a first, typical or preliminary model of something.
A small sample of fabric intended to demonstrate the look of a larger piece.
It's a "set-in" pocket (the pocket opening is cut into the garment rather than applied "set-on" like a patch pocket) that is finished and strengthened with "piping" or fabric "welts" along it's length.
The second step once you have the measurements of someone is to draw out the individual pieces that make up the garment onto paper before making a sample.
The fabric that is used to make the first fit sample is typically made out of a structured fabric called muslin. Prototype is just another word for a first sample, proto, fit sample etc.
When I go hunting for new materials typically I won't buy anything until both my client and I are happy with the material, hence the need to get a swatch or swatches.
Although there can be some variation in what these look like, they are those types of pockets that you typically see on the outside of a blazer or inside for menswear or the back pockets of slack pants. (looks like a little rectangular window)
