Foundations
Point of Pride- Offer free binders to those in need and have a binder donation scheme, and trans feminine shapewear.
Safe2Trans - Offer free binders to those in need and have a binder donation scheme. Linked with GenderGp
Trans masculine
Spectrum- binders, packers, boxers, sensory toys, pronoun products
GC2B- Binders
UnderWorks - Binders
FTM Essential- Binders, Packers, Boxers
Paxsies- Packers
Etsy and local trans Facebook groups are also really good for all of the above products. My personal favourite site is Spectrum because their binders seem to work best with a large chest as they're a bit less slippy material wise and have higher under arm material to avoid side spillage. I've heard smaller chests seem to work best with GC2B.
MyPackFtm - Comfortable, discreet packing straps
Trans feminine
Leos Lines- Very accommodating custom bikini Etsy store
