Aurora Wireless Bra
The Aurora Wireless Bra by Miiyu by Simons is a Canadian-designed women's bra featuring wireless molded foam cups for moderate support and a smooth, seamless look under T-shirts. It is made from a soft recycled nylon microfibre blend, with thin multi-position adjustable straps that can be configured for a racerback fit and a two-hook back closure. Matching panties are sold separately.

Product Insights
The Miiyu Aurora Wireless Bra offers versatile strap configurations (regular, racerback, crisscross) at 39 CAD, but its durability depends on meticulous care: hand washing in cool water and air drying flat are required to reach 100-120 wears per bra, while machine drying with any heat permanently damages the polyurethane foam cups, and machine washing is only safe with a rigid plastic sphere. Rotating among at least three bras extends cup lifespan beyond 100 wears, and hand washing preserves strap elastic.

Buying Guide
1 comparison · 4 sourcesUses
All-day everyday comfort
Per customer reviews, this ultra-light wireless bra is a go-to for all-day work or travel — many say it's so comfortable they barely notice it on. One repeat buyer reports it holds its shape and comfort through frequent washing. Reviews note the band runs small, so many people size up, and some find the fabric too warm in hot weather.[1]
A smooth, line-free look under t-shirts
For wearing under t-shirts, this wireless bra is designed to stay out of sight: reviewers describe its smooth, seamless construction as disappearing under fitted tops. Some reviewers also note the bra's flattering shape under clothes has earned them compliments.[1]
A wire-free bra for shoppers who avoid underwire
The Aurora Wireless Bra is designed without wires, and reviewers who prefer wireless styles or dislike underwire report liking it. Some reviewers who are used to underwire support found it lacked the structure or support they wanted, so it may suit those prioritizing a wire-free feel over firm support.[1]
Product comparison
Compared within this brand.
| Aurora Wireless Bra: Choose this if you strictly avoid underwire and want an ultra-light wireless bra for all-day wear — reviewers say they barely feel it on, and its smooth, seamless construction disappears under tight t-shirts. Note that the band runs small, so sizing up is common to avoid a tight fit. Some reviewers also find the fabric traps heat in hot weather, and the straps may not provide enough support for larger busts.[1] | Vela Wireless Bra: Choose this if you want a wire-free everyday bra with moderate support: reviews describe all-day comfort with no underwire poking, seamless moulded foam cups that stay invisible under white tees and light tops, and just enough lift for A and B cups. It comes in band sizes 32 to 38 with A to D cups and eleven colors, in a soft recycled nylon blend with a cotton lining. Note that reviewers with C+ cups or mature figures often report side spillage and shallow cups, and some found the thin straps uncomfortable over time.[2] | Astra Wireless Push-Up Bra: Choose this if you want a wireless bra with a defined, boosted shape: it pairs moulded push-up cups with a deep plunging neckline in soft, stretch recycled nylon-blend microfibre, and the brand describes it as perfect to wear under T-shirts. It offers moderate support with adjustable back straps and a two-hook closure, and comes in sizes 32-A through 38-D across five colors, all in the same size range. Note that its generous padding and moderate support may not suit those seeking a lighter lining or maximum support, and a matching panty is sold separately.[3,4] |
