Sizing

What sizes does Underlume carry?
We carry sizes XS through 4X across our core styles. Use our Fit Finder quiz on any collection page to get a personalized size recommendation, or check the Size Guide on each product page.

What if I'm between sizes?
We generally recommend sizing up for the softest, most relaxed fit, or sizing down for a snugger, more supportive fit — the Fit Finder quiz will ask about your preference.

Products & Care

What are your products made from?
Our fabrics are soft, breathable blends designed to move with your body. Full fabric details are listed on each product page.

How do I care for my Underlume pieces?
We recommend a gentle cold-water wash and laying flat to dry to keep fabrics soft and supportive for longer. Check the care label on your item for specifics.
