Frequently Asked Questions

Everything you need to know about your UNDERNEAT experience.

How do I know which size to choose?

Each product page features a detailed size guide with specific measurements. If you are between sizes, we generally recommend sizing up for a more comfortable fit, or sizing down for a compressed look.

What is your return policy?

We offer a 30-day return window for all unworn items in their original packaging with tags attached. Please note that for hygiene reasons, certain intimate apparel cannot be returned if the seal is broken.

How long does shipping take?

Standard shipping typically takes 3-5 business days within the continental US. International orders may take 7-14 business days depending on the destination and customs processing.

Are your materials sustainably sourced?

Yes, UNDERNEAT is committed to ethical fashion. We use a blend of organic cotton, recycled polyester, and eco-friendly dyes to ensure our carbon footprint remains as small as possible.

Can I track my order in real-time?

Absolutely. Once your order ships, you will receive an email with a tracking number and a link to our tracking portal to monitor your package's journey.

Which payment methods do you accept?

We accept all major credit cards (Visa, Mastercard, American Express), PayPal, Apple Pay, and interest-free installment plans through Klarna and Afterpay.
