Fits true to size, i.e. Small (A/B Cup), Med (C Cup), Large (D Cup). This is a traditional triangle top with a super cute plastic lace embellishment (matches the seamless lowrise bottom). The top strap is thicker, with a tie, so it is both comfortable, yet extremely adjustable. The bottom portion of the triangle is adjustable along the strap and also just slightly padded (THO prevention). This top is both comfy and fun.
