I'm very pale and quite rosy, so I struggle to find a bra that's truly invisible under light colored or thin tops. If only the undergarment industry would follow the cosmetic industry and come out with lines featuring tens of shades, this would be easier for us all, but alas they have not yet. Most nudes are a beige that is too yellow and too dark to match my skintone, and therefore are extremely visible under tops you'd want them to be hidden under. This perfectly fits the bill. On me, it looks nude, it's that good of a match! But when it's off, it's clearly a delicate light pink. The lace band gives it a pretty look, while the smooth cups are invisible under tops. I'm not particularly bothered by seams showing as long as it's a color match, but many want a totally hidden bra and this does that quite well. It provides ample support from the powermesh layer under the lace. On me, it's not great at hiding nipping when I'm cold, but that can show through a sweater on me, and I'm not really bothered by it, as I'm always cold and all mammals have nipples. To my delight, it does not have that piece of plastic boning that a lot of manufacturers like to put in next to the underwire. That always kinks on the first wear and then pokes me forever ever after, so I'm in the habit of removing it with a seam ripper whenever I get a new bra, and not having to do so is lovely. The J-hook to convert it to racerback works quite well, and the straps are pretty but also thick enough to not dig into my shoulders. As far as fit, the sizing is fine. There is some gapping, however this is because the shape is off compared to my own, but that's not a fault of the bra - different bras are made for different bust shapes. I have always had quite short roots, and in addition, I've had a reduction and as a result have a shape that is shallow with fullness that seems to change from bra to bra. In seamed bras, I'm usually too full at the top, but in this, I'm too full at the bottom with not enough at the top. This bra seems to be a height mismatch more than anything else, as shortening the straps somewhat helps it fit better, but the cups are overall too tall for my bust. I can tell that going down in size would not result in a better fit, as I do fill it out when I've just scooped & swooped then stood up, before I start slipping down into the cups. The fit is a bit better when I use the J-hook, so perhaps the cups are designed with the expectation of having that engaged. This seems ideal for someone who is shallow and center to top full, but with longer roots. It doesn't dig in under the arms, and the straps don't sit so far out on my shoulder that I'm constantly pulling them up unless I shorten them to the point of pain, which are constant gripes that I have with bras, so I'm willing to work with the minor fit issues and use cutlets or padding to fill out where I can't, since this is one of the few decent bras I've come across that isn't painful. Coming from the cheap cotton Fruit of the Loom bras I was wearing all summer because it was just too hot to wear synthetics, this initially seemed quite pointy and East-West, but after a day I was used to it and it looks normal.
