Frequently asked questions
What sizes does Underlume carry?
Every Underlume style is available in sizes XS through 4X, at the same price point — extended sizing isn't a separate collection here, it's just the collection. Bands run 30–46 and cups AA–H depending on the style.
How do I find my correct bra size?
Measure around the fullest part of your bust and just underneath it, braless or in an unpadded bra. You can also take our 60-second fit quiz, or check the full size chart on any product page.
What is Underlume's return policy?
You have 60 days from delivery to return or exchange anything for any reason — worn, washed, whatever. Free return shipping is included on US orders.
Does Underlume offer free shipping?
Yes — all US orders over $75 ship free. Orders under $75 ship at a flat rate calculated at checkout.
What is Underlume's fabric made of?
Our signature cloud-knit fabric is 76% recycled nylon and 24% spandex — buttery-soft, breathable, and machine washable on a cold, gentle cycle.
