Dear customer, each shop's size chart will be slightly different. Please always measure your size according to the size chart referred by each shop. Different size chart is distinguished by the first three digits of the product numbers.
Bust measurements are more important for garments with looser bottoms such as gowns or sleepshirts.
Hip measurements are most important for garments with closer bottoms like slips, pajamas, and panties. Bra size is NOT the same as bust size. One size fits most. If your size is beyond the ordinary size range, order other size ranges.
