Fit Guide
LORAIN SWIM is thoughtfully designed to sculpt, contour, and flatter the body. Because many of our silhouettes are intentionally fitted, some customers prefer to size up for a more relaxed feel.
If you are between sizes or prefer additional coverage and comfort, we generally recommend selecting the larger size.
Please note that each fabric offers a unique level of stretch. Be sure to review the Stretch Guide on each product page for style-specific fit recommendations.
If you're unsure which size is right for you, we're always happy to provide personalized sizing assistance. Contact us at contact@lorainswim.com and we'll help you find your ideal fit.
