This top is simply smashing. I usually wear a Medium, although according to the fabric and texture I could wear a Small. This top is a Polyester Polyurethane blend and has the texture of vinyl which means it is somewhat clingy like the vinyl raincoats. But that just makes it feel compressive and good. The built-in shelf bra is great because you don't have to wear a bra so you have so much freedom and you feel super sexy. The zip up front has the circular spots for each breast. The fabric feels strong. The look is shiny and sheik with this great sheen. When I saw this Crop Top, the Sweater Rib Crossover Top and the Legging in Takara Shine together I just had to buy the ensemble. Wow! it looks simply fabulous. Think about how you can make this ensemble yours.
