ThirdLove Review: Half-Cup Sizes Changed Bra Shopping — Customer Service Hasn’t Kept Up
Excellent comfort and inclusive sizing, but an AI chatbot and refund fees make returns more frustrating than they should be.

01 Why We Reviewed ThirdLove
ThirdLove was founded in San Francisco by Heidi Zak and Ra’el Cohen to fix an old problem: most women wear the wrong bra size. Its online Fit Finder quiz and half-cup sizes (like a 34 C½) made it one of the best-known direct-to-consumer bra brands. It has now processed more than 10 million orders and sells through Nordstrom, Kohl’s, Belk, Amazon and TikTok Shop. Recent launches include TempSync temperature-regulating activewear and lingerie, and silicone nipple covers in 2026.
The honest caveat: Trustpilot reviews are polarised, averaging about 3.9/5 but split almost evenly between 5-star (38%) and 1-star (37%). The main complaints are an AI chatbot that’s hard to get past, return friction, a reported fee on cash refunds (exchanges are free), and promo codes that don’t work. The brand has also shrunk its retail footprint to two California stores.

03 Honest Breakdown
✅ WHAT WORKS
- Half-cup sizes. These fill the gap for women caught between standard cups.
- All-day comfort. The 24/7 line’s memory foam cups and soft straps earn loyal fans.
- 60-day wash-and-wear trial. You can actually wear the bra before deciding.
- Wide size range. Bands and cups cover most of the spectrum, including half sizes.
- Free exchanges. Swapping sizes costs nothing.
❌ WHAT TO KNOW
- AI-first support. Many buyers struggle to reach a human.
- Refund fees. Cash refunds reportedly carry a fee, while exchanges are free.
- Fit for small busts. Some petite-bust customers find cups gape.
- Discount code issues. Promo codes failing at checkout is a recurring complaint.
Overall, the bras are excellent. Plan on exchanging rather than refunding.
