Frequently Asked Questions

How do I use a First Thing promo code?

Pick what you want, like a bra, some undies, and put it in your shopping cart. There's a code box at checkout. Drop it in, click Apply, and watch the price change. One thing to know: this store runs sales a lot, so a code might not work on something already marked down. If you are not in a hurry, then wait for the sale to get extra discounts.

Why isn't my First Thing promo code working at checkout?

Most times it's a small copy mistake, like an extra space. Some codes only work for first orders, so it won't help if you've shopped here before. Sale items and clearance pieces are left out too, so check your cart first. If none of that fixes it, try the code on a single full-price item before you give up on it. Some codes are just for specific products, not just for all, which means if the code is for bras, it will not work on undies. 

Is shipping really free?

Yes, but only on orders over $140. Under that, you pay a fee at checkout. Buying a bra along with some undies in one order can help you reach that amount faster. This also means your promo code and your free shipping can both work on the same order, as long as your cart is over $140 before the code is applied.

Can I return undies if I don't like them?

Undies and bottoms can't be returned; that's for hygiene. Bras and tops are different; you can send those back within 30 days if the tags are still on and nothing's been worn. The item also needs to go back in its original packaging, so it's worth keeping that until you know you're happy with the fit.

What is Checkout+?

It's a small $2.98 add-on. Pick it, and any return or exchange later is free. Skip it, and you'll pay a $9.99 fee if you need to send something back. If you're buying a size you haven't tried before, adding Checkout+ at checkout can save you money if it turns out you need to swap it.

Can I get my money back on a sale item?

Not in cash. Sale items only come back as store credit, not a refund. Clearance items can't be returned at all. Because of this, it helps to double-check your size using the fit guide before you buy anything already on sale.

Does First Thing have anything for pregnancy or after birth?

Yes, there is a maternity and nursing bra range built for a changing shape. These bras are made to stay comfortable through pregnancy and to make feeding easier once the baby arrives. A First Thing discount code can be used on this range too, as long as the items aren't already reduced in a sale.
