I bought a White and Mauve XL, wish I tried one a size smaller. I'm 5'feet 9.5" tall wear L-XL Tall with bra size 36-38 DD-DDD depending on the cut or sculpting. These are 2 ply, stretchy, soft, unlined, light support like a sleep bra or lounge around the house bra. If the fabric were just a bit st...urdier they'd be aces for me. They're a flattering silhouette, no seaming to force 'spill over' lines, If I sized down, the cups wouldn't have much coverage, but having sized up, I find the straps are long. It'd be dreamy if they were adjustable I'll probably sew them shorter toward the back for a little 'hoist.'. The straps are comfortable, width distributes weight - zero seam digs or aches at shoulders or neck. But then, these are gentle support not forklifts, lol. The bottom band rolls a bit if I slouch, only several elastic strips between the layers. I don't get squish lines anywhere, no uni-bewb, no cut circulation or sweat in my sleep. Nice to have. On sale is a steal. Try one!'
