I’ve always wanted to love the Wazzie Wool bralettes that Oiselle has produced for the last few years. I loved the feel of the Wazzie Wool against my skin but the fit of the bralette was always SO uncomfortable, whether I sized up or sized down or ordered my usual O size. I was constantly fantasizing about a Wazzie Wool bra that did not have adjustable straps and had more of a racer back fit. When this Wazzie Wool Crossover bra was introduced, I knew I had to have it. It is everything I hoped for and more! The fit is amazing and so comfortable. I can hardly feel it on my body it feels so good! I lounge in it, sleep in it, do yoga in it. It’s not very supportive so it probably wouldn’t work as a running bra but if you have a small bust size, it might work for me. As for sizing, I suggest ordering your regular O bra size. I normally wear a size 2/XS in O bras and the XS fits perfectly (unlike the Wazzie Wool bralette, where I had to size up to a size S). My only complaint: the odor. This bra stinks! But I’ve owned many wool products and am well aware that wool has an odor that goes away after the first wash. Do yourself a favor and buy yourself one of these for Xmas. You made it through 2020: you deserve it!
