Our sizing chart has served clients over the years. It’s not perfect but provides a good sense of how our sizes run. It’s hard to be accurate because of the Lycra stretch factor. The important thing to note is that Brazilian sizes tend to run one size smaller so a US Small is sold as a Medium in Brazil. Most of our tops have adjustable back and shoulder straps so if you’re in between sizes, you can still get that perfect fit. You can’t generalize with sizes but it’s fair to note that our XS is ideal for petite women. Perhaps young teenagers or Asian women. Our Small and Mediums fit comfortably for most women between the ages of 18-35 years of age and our Large size is suitable for slightly larger women but not necessarily overweight.
