Classic Brasil Sul top with wide criss-cross straps & low ballet-style back. Body hugging size M 12" across/24" around all the way down, 15.5" neckline-waist. Brazilian supplex 88% polyamide 12% elastine & 100% polyamide full lining. No shelf bra but very supportive. I wear a B & don't need a sports bra, but it depends on size, activities & preferences. Love this top but I have too many. Excellent condition, no visible wear or damage. Looks great with yoga pants, jeans, or shorts. Same as the aqua top posted.
