This bra is not actually a technical "good fit" but it is very comfortable. I can just wear it without having to adjust or notice discomfort. The band is on the looser side and of course the cups do not have enough depth at the wire, consequently, they settle down lower that my IMF. (because, yes, it's a molded cup)
My search for a plunge that fits well enough for two hours continues. This is the fourth 458000 I have owned: it has admirable characteristics.
You will notice my previous reviews labeled this bra as wide and shallow. After 170+ bras, I stand corrected. The wires are average in width and the immediate projection is good as is the apex projection. This bra is designed for taller roots and less center-full breasts. Shorter roots will find gaping near the strap. And, center full breasts will quad. The lift, however, is excellent.
It has lovely, subtle details that I appreciate such as a small, shimmering tulle ruffle along the top of cups and base of band, stretch lace side panels, and double straps (front half of strap). The padding is sufficient to hide prominent nipples. Although this is too small for me, it gently lifted my FOB breasts into round mounds. The gore, straps, and band are quite comfortable.
