Frequently Asked Questions

Does What Waist offer refunds if an item doesn't work out?

No, What Waist doesn't issue refunds. Instead, eligible items can be exchanged or returned for store credit within 30 days of purchase, which is worth knowing before you buy if you'd rather get cash back than credit toward a future order.
 

Which items are excluded from What Waist's return policy?

Underwear, supplements, and items purchased during special sales events aren't eligible for return or exchange, so double-check sizing carefully before ordering anything in those categories.
 

Do I have to pay for return shipping on a What Waist exchange?

Yes, you're responsible for shipping costs both to send the item back and to receive your exchange or replacement, since What Waist doesn't cover return shipping fees.
 

What condition does a returned item need to be in?

Items must be unworn, unwashed, and free of odors, marks, or stains, with all original tags attached and packaging intact. If a returned item shows signs of wear during warehouse inspection, the exchange or credit will be denied and you'll be responsible for having it shipped back to you.
 

Can I combine a discount code with What Waist's sale items?

Not always. Items already discounted through a site sale, especially anything marked down 30% or more, are often excluded from further promo codes and are typically final sale, meaning they can't be returned or exchanged at all.
 

How do I start a return or exchange with What Waist?

Submit a request through What Waist's online return form along with a copy of your order confirmation. Once approved, you'll receive instructions for sending the item back to the correct warehouse address.

 

Does What Waist offer a discount for first-time customers?

Yes, a percentage off your first order is commonly available through a sign-up promotion or a code shown on the homepage, so it's worth checking for that before completing your first purchase.
 

Why did What Waist deny my exchange?

The most common reasons are the item showing signs of wear, missing original tags or packaging, or falling into an excluded category like underwear, supplements, or a final sale item, so reviewing the return conditions closely before shipping something back can save you the shipping cost of a denied return.

Saving Guide

Use the size guide closely before you buy:

Since underwear can't be exchanged at all and other items need to arrive back in new, unworn condition to qualify for credit, getting your size right the first time avoids the shipping cost and hassle of an exchange altogether.

Grab the first-order discount if you're new to the brand:

A first-time customer discount is typically available through a sign-up prompt or homepage code, and stacking it with your very first purchase is usually the easiest discount to claim since there's no prior order to exclude it from.

Think twice before buying deep sale items you might need to size up or down on:

Items marked down 30% or more are usually final sale, meaning a sizing mistake there can't be corrected through an exchange, unlike a regular-priced item.

Keep tags on until you're sure.

Because items need original tags attached and no signs of wear to pass warehouse inspection, holding off on removing tags until you've confirmed the fit protects your ability to exchange it if needed.

Factor return shipping into your decision to order multiple sizes.

Since you pay shipping both ways on an exchange, ordering one size you're fairly confident about, rather than several sizes to compare, usually costs less overall than the combined shipping fees of sorting it out through returns.

Before you buy, check:

Whether the item is excluded from returns (underwear, supplements, or a special sale), whether a first-time discount code is available, and whether you're confident enough in your size to avoid needing an exchange at all.
