If you are not familiar with the brand and already know your size. Please research these for the proper sizing since they do run differently from a normal bra. The Angelina cup provides an ideal base to accessorize with any back strap and/or shoulder strap. These cups can be worn with a back strap for a strapless bra that stays in place, or with a back strap + shoulder strap for a complete bra look. Sizing Tip - if you are in between sizes, we recommend sizing down as these cups tend to run big.
