First, add your favorites—whether it's a cozy bra, comfy briefs, or the perfect pair of pajamas—to your cart. When you’re ready to check out, click the bag icon in the upper right corner of the screen. A pop-up will appear on the right. Scroll to the bottom of that pop-up and click “Checkout.”

NEIWAI is giving you two chances to save 15% on your first order. Here’s how to grab your discount.

Prefer to get your deals via text? When you sign up for NEIWAI’s SMS updates, you’ll get a promo code for 15% off your first order.

To sign up, go to neiwai.com, scroll to the bottom of the page, and click the black tab in the lower-left corner that says “Activate 15% Off.” A pop-up will appear asking for your phone number. Use the flag icon to select your country, enter your number, and click “Activate 15% OFF.”

Once you’re signed up, your code will be sent straight to your phone, along with updates on new arrivals and exclusive offers. If you ever want to unsubscribe, just reply STOP to any message.

Refreshing your basics just got a whole lot easier and more affordable. NEIWAI’s mix-and-match collection is perfect for stocking up on pieces you’ll want to wear every day. Featuring items from the Barely Zero line in soft neutrals, pastels, and earthy tones, it’s the ultimate way to update your essentials.

And here’s the best part: buy two items and enjoy 5% off or grab three or more to score 10% off your order. It’s a simple way to save while giving your basics a fresh upgrade.

If you love earning rewards while shopping, NEIWAI’s Collective program is the way to go. As a member, you’ll earn one point for every dollar you spend, plus bonus points for activities like reviewing items, referring friends, and following NEIWAI on social media. You’ll also get special birthday perks and exclusive discounts.

Here’s how the points break down:

—200 points = $10 off your next order

—300 points = $15 off or a free pair of briefs

New members start at the Lounger tier, which gives you early access to new arrivals and promotions. Reach Insider status by spending $200 annually, and you’ll unlock free standard U.S. shipping and access to points multiplier events. Spend $400 a year to hit Elite status, and enjoy VIP gifts and exclusive luxury experiences.

A couple of things to keep in mind: Points are valid online only, and rewards are good for 90 days.

Who doesn’t love free shipping? When you spend $50 or more at NEIWAI, your order ships on the house. And if you’re an Insider or Elite member of NEIWAI Collective, you’ll get this perk too.

If you're just shy of that $50 mark, you'll pay a flat $10 for shipping. Keep in mind, if your order is coming from overseas, there could be additional fees or longer delivery times, but you’ll see all of that when you check out.

Black Friday might still be a little while away, but it’s never too early to get excited for NEIWAI’s biggest sale of the year. Last year, we saw up to 30% off sitewide, and we’re expecting similar savings this time around. The sale typically starts a few days before Black Friday and runs through Cyber Monday, so be sure to mark those calendars. It’s the perfect time to grab your favorite basics or get a head start on your holiday shopping.
