Fits Like A Glove

I’ve been wearing two Sieve Non-Wire bras for the past year and a half and decided to give the wired a try. Comfortable and supportive, they do provide a lovely shape and confidence-boosting support with all the comfort of the Non-Wire bra. I love the 3 prong band which provides comfort without the bulkiness I’ve experienced with other brands. Sexy, simple, and perfect. Couldn’t recommend more highly.
