sizing guidelines
There are no uniform sizing standards in the apparel industry. Sizes, shapes and fits will vary from brand to brand. Therefore, we suggest you use our size charts below as a general guide only and not as a definitive size listing for any one item. We provide measurements for many items in our product descriptions.
When a bust or waist measurement is listed for one size, you can determine the measurements for other sizes by adding 2 inches per size to the number listed. For example, if a bust measures 38" on a size 1x, the 2x will be 40" and the 3x will be 42". Lengths are generally consistent across a size range. If a size 14 item has a length of 31", it is likely that the size 26 will also have a 31" length. The size chart is a general guideline and not a definitive measurement for all the items listed on alight.com.
