Pop and Pop Up have different size charts. Enter your full everyday bra size, including band and cup, and select the product before reading the result. A VELUNA letter is a product size, not a bra cup letter.
Size is only one fit check. Pop needs a suitable tight, structured garment and low, outer placement. Pop Up needs coverage over the adhesive cups and front clasp. A correct chart match cannot promise invisibility under every neckline.
Find your size and follow the illustrated wearing steps.
