Size Swap Policy
Effective Date: April 26, 2026 · Last Updated: April 26, 2026
At LillyWears, we want you to feel confident and comfortable in every piece you wear. Finding the perfect fit can take a little trial and error, especially when shopping online. That’s why we offer flexible Size Swap options to make sure you get the right size without the stress.
Important: check your size first
Before placing your order, please:
- Review our detailed Size Guide with measurement instructions
- Check the size chart on each product page (sizes may vary by style)
- Take your bust, waist, and hip measurements accurately
- Compare your measurements to our charts (not just letter sizes)
- Many items follow international sizing (1–2 sizes smaller than typical US sizes)
Not sure about your size? Contact us BEFORE ordering:
- Email: [email protected]
- Phone: +1 (415) 483-2507
- Hours: Monday–Friday, 09:00–16:00 EST
Taking 60 seconds to verify your size now means you get the perfect fit immediately, no waiting, no extra fees, no hassle.
Option 1: Keep It Swap (recommended)
Ordered the wrong size? Keep your item and we’ll send the right one!
Instead of waiting weeks for a traditional exchange, we offer a faster, easier solution: keep your original item (gift it, donate it, or save it!) and we’ll send you the correct size right away.
How it works
Step 1: Contact us within 14 days of delivery:
- Email: [email protected]
- Phone: +1 (415) 483-2507
- Hours: Monday–Friday, 09:00–16:00 EST
Step 2: Choose your shipping speed:
- Standard Shipping: $9.99 (10–15 business days delivery)
Step 3: Keep your original item — it’s yours!
Many customers:
- Gift it to a friend or family member
- Donate it to someone in need
- Save it for postpartum or weight changes
- Keep it for layering or different occasions
Step 4: Receive your new size with full tracking via email.
No returns. No waiting 4–6 weeks. Just the right size, fast.
Eligibility for Keep It Swap
- First size swap only (one per customer per order)
- Request must be made within 14 days of delivery
- New size must be in stock
- Available for orders shipped to US addresses
- Must have reviewed our Size Guide or product size chart before original order
Items eligible for Keep It Swap
Most LillyWears products qualify, including shapewear, bodysuits, swimsuits, loungewear, and pants/skirts.
Items not eligible
For hygiene and safety reasons, Keep It Swap is not available for:
- Final sale or clearance items (marked as such at checkout)
- High-value items over $100 (traditional exchange only)
Why we offer this
We’d rather you have two pieces that work for you than waste 4–6 weeks shipping items back and forth internationally. This sustainable approach reduces shipping emissions and gets you the right size faster.
Option 2: Traditional size exchange
Prefer not to pay shipping? We also offer free traditional exchanges.
If you don’t want to keep the original item, you can exchange it the traditional way at no cost to you.
How traditional exchange works
Step 1: Contact us within 30 days of receiving your order:
- Email: [email protected]
- Phone: +1 (415) 483-2507
- Hours: Monday–Friday, 09:00–16:00 EST
Step 2: Provide your order details:
- Order number
- Item(s) you’d like to swap
- Size you originally ordered
- Size you’d like to exchange for
Step 3: Our team will check availability and send you return instructions and a prepaid return label (for US customers on first exchange).
Step 4: Pack the item securely in its original packaging, include any return forms provided, and ship it to the address we provide. We recommend using a trackable shipping method.
Step 5: Once we receive and inspect your return, we’ll ship your new size and email you a tracking number.
Shipping costs for traditional exchange
- US customers, first exchange: Free return label + free new-size shipping
- Subsequent exchanges or international orders: Customer pays return shipping (typically $15–25); new-size shipping is always free from LillyWears
