It's really well fitting, holds the boobs in place and looks fantastic under sheer tops. It's soooo hard to find non-underwire bras of any kind in J cup especially when you have a small band measurement (28). Why do bra makers think that people with a large bust like having metal underwire digging into their ribcage all day?! We don't please make more non-underwire styles in 28J and above!
For me the support is good enough for daily wear, maybe don't run down the stairs at full speed though. It doesn't provide a super separated boob look but I'm fine with that, I imagine that look is hard to achieve without underwire.
Only gripe is that the slightly bulky line of stitching on the strap falls right on the shoulder and so after a full day holding up a pair of heavy boobs, it does leave a mark on the shoulders where it has been digging in. Also, the longline of the band rolls up a little bit but personally doesn't bother me much.
All in all, 100x more comfortable than a normal underwire bra, please make in more colours!
