I am so happy to find this bra (and Lula Lu!). The underwire is very comfortable, and I like that the padding is more like a lining as opposed to a life preserver :) . I find the shape is very natural, which in my experience is hard to find in smaller sizes. I like that this bra gives a boost and some shaping without looking fake.
For comparison, I also bought the Dahlia Microfiber Wireless Bra in the same size. I find that the fit is consistent between this one and the Dahlia, i.e. the cups are the same distance apart and I wear both bras on the loosest hooks. I also bought the Convertible Racerback, which was a lovely bra with similar quality of construction to this one, but found that the band was too small for me to wear comfortably.
