I'm currently stymied at finding a perfect solution for what to wear to work. Here's what I've tried so far. My measurements are 33"/36" under/across.
Compression shirt (S): does compress down to 35.5", but pinches hips.
Road Runner Sports Powertek A/B
(L): does compress down to 35.5", but has thick racerback straps that show through my tighter shirts (and through my looser shirts too if I bend over)
Chasse Multi-Color Performance Tank
(M): no compression, rough fabric
NYDJ City/Sport Seamed Trainer
(S): no compression, bulky fabric, irritates nipples. (And that's not a typo: I'm a small!)
Necessity Athletic Performance Tank
(XL): not only no compression, but makes them stick out more and bust goes up to 36.5". But it does prevent road bounce pain and is super-comfy so I wear it with my looser shirts and to bed.
So the current protocol is with my tighter shirts I wear a compression shirt, and with my looser shirts I wear an NYDJ (and use silicone nipple covers for protection). On days where I'm working alone I'll wear a looser shirt with a Necessity.
Does anyone know of something with a shelf bra that compresses as well as the Road Runner Sports while having an inconspicuous full back like the Chasse/NYDJ/Necessity? Road Runner Sports does have this
but it has huge seams in weird places that would show through.
