Frequently Asked Questions
Everything you need to know about your Underoutfit experience.
How do I determine the right size for me?
We provide a comprehensive size guide on every product page. If you are between sizes, we generally recommend sizing up for the most comfortable fit, as our fabrics are designed with high-performance stretch.
What is your return and exchange policy?
We offer a 30-day 'Comfort Guarantee.' If you aren't completely satisfied with your first purchase, you can return or exchange it within 30 days of delivery, even if the tags have been removed.
How long does shipping take?
Standard shipping typically takes 3-7 business days within the continental United States. Expedited shipping options are available at checkout if you need your items sooner.
How should I care for my Underoutfit garments?
To maintain the integrity of the fabric and elastic, we recommend machine washing on a cold, gentle cycle and hanging to dry. Avoid using bleach or fabric softeners.
Can I modify or cancel my order after it has been placed?
Because we strive to process orders as quickly as possible, there is a very limited window to make changes. Please contact our support team immediately if you need to update your shipping address or cancel an order.
What payment methods do you accept?
We accept all major credit cards (Visa, Mastercard, American Express, Discover), as well as digital payment options like PayPal, Apple Pay, and Google Pay.
