I gave up on the Fortnight Luna bra after many failed trials - the cups cut in, sizing up just made them wider and taller, I even tried a few different colors.
I wasn't sure I would have any luck with Mira since many reviews say they're similar, but I like this one! It's stretchy cup fabric seems to suit my shape better than the mesh on the Luna. Perhaps it has a tad more give. The cutting in on top is reduced for me as well. It's a bit wide on me, but overall I love it!
The Mira is a very pliable and soft, soft bra. This one honestly feels like a luxury bra. Despite this, because it is constructed with stretch lace, it does next to nothing for support. I find this one easy on the band, but I honestly just think the way the elastic is attached is what bothers my skin - I don't think other people are as sensitive to elastic as I am, though. I think this is best used as a sleep bra or a "special occasions" bra, as it creates a low and wide profile that I personally don't like under clothes. However, my boobs are pretty heavy and are not self supporting at all. It's a very comfortable and beautiful bra, but doesn't do anything for me, unfortunately.
