Size Chart We carry a wide variety of different styles and many different brands. For this reason we are not able to offer an one size fits all size chart. Typically our sizes run larger than department store sizes. Our average top has 38" M bust measurement. Styles that have a 38" M bust measurement correlate approximately to S (6-8) M (10-12) L (14-16) XL (16-18) 2XL (18-20) 3XL (22-24) Bust and length measurements are posted for each style for a size M, there is a 2" difference in the bust measurement between sizes. Bust measurements are taken by laying the shirt flat (unstretched) and measuring from armpit to armpit, that measurement is then doubled. Length is measured from shoulder seam to hem.
