* Non-wire bra sizing can vary by preference and if you're toward the top of a size range and prefer more coverage, you may want to size up. For styles available in + sizes (designed with additional support details for our larger cup customers), we find DD's can be on the cusp - if you prefer more coverage and support, we suggest the + bra equivalent for your band size.

When it comes to wireless bras with support, Sieve is our favorite fabric. Our Belgian power micromesh makes the most supportive bras, all the bulk of extra padding or lining. This fabric is as close as it comes to magic — it’s comfortable, smoothing, sexy and sheer, and does an incredible job providing lift and shape.

We make a variety of best support bras — starting with our #1 best selling style, our Sieve Non-Wire Bra. If you’re interested in wirefree comfort and a deep v plunge neckline, the Sieve Triangle Bra is the perfect match. Lastly, for our most supportive style, our Sieve Demi Bra provides the same airy light feel, with lots of support, and the extra shaping and lift of an underwire. These styles are beloved by DDD and G cups and from 30 to 42 bands. Don’t be fooled by their minimalist aesthetic, these bras do a lot with a little. Trust us, you’ll be surprised at the strength of a power micromesh ;) We sure were when we first discovered it, and today, these styles have over thousands of 5 star reviews for a reason.

Don’t forget to complete your set with our Sieve underwear bottoms — from high waist briefs to low rise thongs, we have a perfect match.
