ThirdLove’s documented strength is precise fit through half-cup sizing. ThirdLove says its 24/7 Classic T-Shirt Bra was the first bra made in half-cup sizes, offered across more than 60 sizes from 32A to 44H, with ultra-thin memory foam cups and non-slip straps. Reader’s Digest reports the bra has sold more than three million units and earned more than 33,000 five-star reviews. Harper’s Bazaar says if you buy just one T-shirt bra, it should be this one, calling half sizes a game changer for gape-free coverage.
ThirdLove, based in San Francisco, also sells wireless, unlined, sports and coverage bras plus underwear. ThirdLove lists the 24/7 Classic T-Shirt Bra at about $72 to $74, and its wireless bra page mentions a 60-day guarantee. Hip2Save’s two-year review praised the brand’s half sizes and noted shipping adds $5.99.
On Trustpilot, ThirdLove scores 3.8 from 169 reviews, with 38% five-star and 37% one-star ratings. Trustpilot’s AI summary says customers praise helpful, knowledgeable service, comfortable materials and accurate sizing guides. LeeAnn Erickson (US, 5 stars) said a fit stylist helped her find a better size. Kristen Rushing (US, 5 stars) called them the only bra she’d own. ThirdLove replies to every negative review, typically within a week.
The honest caveat: the return process frustrates many reviewers. D P (US, 3 stars) said each returned order carries a $4.99 processing fee. Patricia Priest (US, 1 star) described a cumbersome return involving an AI agent. SK (US, 1 star) and Mrs. Rhonda Townsley (US, 4 stars) disliked the AI front line. Thingtesting reviewers mention inconsistent sizing and thick or hot materials.

Full Review Breakdown
Fit and Half-Cup Sizing
ThirdLove’s half-cup sizes address the gap between standard sizes. Harper’s Bazaar called half sizes a game changer for gape-free coverage. LeeAnn Erickson said a fit stylist helped her find a better size. Suramom (US, 5 stars) felt bras don’t suit smaller busts unless the band is very narrow.
Comfort and Materials
Reviewers praise comfort and fabric. Kristen Rushing said the bras are so comfortable and worth the cost. Thingtesting reviewers mention thick or hot materials for some styles.
Customer Service
Service is a strength. Cynthia (US, 5 stars) said an agent applied a forgotten discount. Johanna Meier (US, 5 stars) received an unexpected credit. Some reviewers dislike reaching an AI agent first.
Returns and Fees
Returns are a common complaint. D P said each returned order costs $4.99. Janice Z. (US, 1 star) struggled with a return for a third-party order. ThirdLove says it refunded fees in some cases.
Best Products Worth Buying
ThirdLove’s bestseller with memory foam cups, half-cup sizes and 60+ sizes. Harper’s Bazaar’s top pick for small busts. Best for everyday wear under fitted tops. Trade-offs: try the fit finder first.
An unlined bra praised for freedom and support. Best for natural shape. Trade-offs: less coverage than lined styles.
A structured wireless bra using standard, + and ++ cup increments. Best for underwire-free comfort. Trade-offs: Thingtesting reviewers report sizing inconsistencies.
ThirdLove’s most affordable popular style. Best for budget-friendly comfort. Trade-offs: less structured support.
What Customers Actually Think
“Great bras, the best. So comfortable and worth the cost.” — Kristen Rushing, Trustpilot reviewer (US, 5 stars, ThirdLove bras)
“I really like this minimized bra a lot and I’m excited to get the replacement in the perfect size!” — LeeAnn Erickson, Trustpilot reviewer (US, 5 stars, minimizer bra)
“The feature to pick your size was very accurate and the product was good quality.” — Kathleen Shanley, Trustpilot reviewer (US, 5 stars, ThirdLove order)
“Just be aware that each returned order charges a $4.99 processing fee even if you ship multiple orders together in one box.” — D P, Trustpilot reviewer (US, 3 stars, returns)
“I would prefer to actually speak to a live agent, but that doesn’t seem possible.” — SK, Trustpilot reviewer (US, 1 star, exchange)
Is It Worth It?
Yes, especially if you fall between cup sizes. Use the fit finder, buy during sales, and factor in the $4.99 return fee if you’re unsure of size.
