About Subset
Subset, which launched in 2018 as Knickey, makes organic cotton underwear, soft bras, lounge and socks for women, plus underwear and lounge for men.
Its multi-pack bundles are already discounted in the cart, yet a bundle discount cannot be combined with any other code, so the real choice is between the bundle price and a single code.
Subset is led by founders Cayla O'Connell Davis and Lauren Sagadore, who bring backgrounds in product development, supply chains and sustainability. The company took the Subset name in 2023, widening its range from organic cotton intimates to everyday innerwear, and many products are marked with Global Organic Textile Standard certification. It publishes impact reports and has a recycling page.
Women's underwear comes in thongs, bikinis, briefs, hipsters, boyshorts and maternity styles, sorted by rise and coverage, and bras include the Keyhole and Triangle Soft Bras plus a scoop bralette. Lounge pieces include the Essential Robe, Classic and Boxy Tees and the men's House Pant, and seasonal colors such as Terracotta appear in limited runs.
When shoppers look for Subset coupons
Subset coupon searches peak in April, about 1.7× a typical month, and dip lowest in November.
Does Subset offer free shipping?
Yes. Orders over $75 ship free; below that, Economy costs $5 up to $20 and $8 from $20-$75, while Priority is a flat $12.
How long does Subset shipping take?
PO boxes, Alaska, Hawaii, Puerto Rico and the USVI are covered, but nothing ships outside the U.S. and its territories since April 15, 2025.
What is Subset's return policy?
30 days from purchase for an exchange, store credit or refund; exchanges and credit travel free, while refunds lose $8 for return shipping.
What payment methods does Subset accept?
Visa, Mastercard, American Express and Discover cards, plus PayPal, Apple Pay, Shop Pay and Shop Pay Installments through Affirm.
More about shopping at Subset
- First Pair Guarantee
- One pair of each underwear style and size in a first order can be tried risk-free, with quality concerns handled within the first year.
- Clearance rules
- Clearance underwear is final sale, and clearance bras and lounge pieces can only be exchanged, never refunded.
- Email welcome
- New customers joining the email list receive a one-time 15% off code for their first order.

How to use a Subset discount code
- At Subset, bundle discounts appear on their own in the cart once a qualifying multi-pack is added, while every other discount code is typed in at checkout.
- Only one code fits per order, and a bundle discount blocks any additional code, so a 3-pack of socks at $30 and the 15% welcome code cannot both apply.
- That welcome code comes from joining the email list as a new customer, so the sign-up belongs before the first order is built.
- Rewards points behave the same way: they convert to a discount on a later purchase but cannot be combined with another discount code.
If your Subset code doesn't work
- One code per order: One discount code per order; bundle discounts cannot be combined with any other code.
- New customers only: 15% off a first order (sign up for the email list as a new customer to get a one-time code) does not apply to repeat orders.
- Where to enter it: Bundle discounts apply automatically in the cart; other discount codes are entered at checkout.
More reasons a code fails, and what to try: why promo codes don't work.
More ways to save at Subset
- Bundles are the built-in saving: 3 pairs of socks for $30 or 3 men's underwear for $80 undercut buying the same style one at a time.
- The clearance section lists pieces at up to 50% off, with the catch that clearance underwear cannot be returned.
- The Rewards Program and referrals add points toward a future discount, and a free scrunchie currently comes with purchases over $99.
- Choosing an exchange or store credit over a refund also avoids the $8 return shipping fee.

Does Subset have a first-order discount?
New customers who join the email list get a one-time code for 15% off the first order.
When does Subset shipping become free?
U.S. orders over $75 ship free. Smaller orders pay $5 or $8 for Economy depending on the order total, or $12 for Priority.
Is Subset the same brand as Knickey?
