The Bijou features smooth cups and a unique detachable sweetheart racerback detail to be worn in multiple ways including halter and t shirt. However, if you want to wear the bra without the special heart racerback detail, it fully detaches and can be worn like a regular bra. This little demi cup bra also features contoured push up padding for a major boost. Bijou has a front closure and is available in C cups. To achieve the best fit and comfort take advantage of the adjustable straps. There are 3 adjustors on the detachable detail, so make sure you adjust in all 3 places for a better fit. Since the bra is a front closure bra, you have less flexibility on the band size. Since The Little Bra Company is made especially for petite figures, the band size is cut smaller than other generic bra brands. For example, if you are currently wearing a 32A in another brand, and the bra fits a little loose, then a 32A in Isis should fit you better. However, if a 32A fits you tight to just right, you might want to go up a band size in this style.
