Beyond Yoga Women's Slim Racerback Cami Tank - Soft Stretchy Workout Top for Yoga, Gym & Lounge Wear - Comfortable Athletic Shirt for Women's Fitness & Casual Outfits

I got a large and it fits like most of my other, similarly styled tops from different brands in size medium. For reference, I am a 36A and feel like a medium may be too tight around the rib cage; no problems with gapping/ loose fabric at the chest so this is a safe bet for smaller chested gals. Great breathable fabric with a soft, glorious feel and superb stretch. Very comfortable! Has held up to several wears and washes with no loose threads, pilling, shrinking, or shape distortion. I love that it's longer in length and stays put. The green color is very nice. I think this is one I'll consistently grab first out of the pile. Perhaps one isn't enough!
