I have had some similar problems finding proper support… I did however find amazing bras from Patagonia its their Women’s Active Mesh Bra.
The description is this:
“Get the Patagonia Women’s Active Mesh Bra for all of your summertime activities. This comfortable sport bra wicks perspiration away from your skin so you stay dry and cool during summer hikes or heated yoga sessions. Stretchy fabric and seamless construction let you move without restriction while supportive V-shaped straps stay put. Patagonia made the Active Mesh Bra so it could be worn alone or as a foundation layer in any weather.”
It’s a bit thicker but that gives you the support if you are bigger chested. The price may be a bit high ($35) but I got mine at an outlet for $13 bucks each. They are so comfortable I would highly recommend them!
