I’m an " after-market " 32DDD & really like the Shefit bras because they’re infinitesimally adjustable. Unfortunately, they wear out fast due to that same reason. Victorias’s Secret, Lululemon, & several others offer a double-layer sports bra with an underwater on the inside & a zip-up compression layer on the outside. I’ll probably try that next. I have a drawer overflowing with bras because what works for yoga doesn’t work for riding & jiu jitsu requires something all together different!
A woman on Shite Eventers vet wrapped her boobs when she forgot to bring a sports bra to change into. She said it worked well! Worth a shot.
