Many of these shops offer multiple items but I have them categorized based on what I usually check them for. Notes on each shop

Trans Affirming Clothing

Shops that are specifically for gender affirming clothing care. There are a couple more with the general shops that have compression garments as well.

Favorite compressive underwear store: leolines ←expensive but the best I have found
Binder store: gc2b
Swimwear, compressive tops (much more comfy than binders, safe for excercise): outplay
Assorted trans wear: Origami Customs
TomboyX commonly comes up. I tend to avoid them and recommend against them because they have history of not dealing with transphobia towards their models.
Trans Missie - lots of stuff for transmasc and transfemm people. Binders, swimwear, packers, compression garments (including swimwear), prostheses, and uniquer stuff (like shoepads)
Carmen Liu - UK’s first lingerie brand for tucking underwear, also have bras
Shapeshifters - binders, and a binder dress :)
