I bought this bra after reading reviews that it ran small enough to be a 28C. I measure as a 26D and this bra is too big in every way. I found the band to be more stretchy than other 30Bs I own. The band length is longer than other 30-band Lunas on Bratabase. I bought this bra during the boxing day rush, so perhaps the quality isn't up to par.
Other than the sizing, I found all the seams to be a bit itchy. Not too much that I need to scratch, but it's noticeable throughout the day. Also, the cups are made of mesh, so there is nipple show-through.
I love this bra but I wish I had sized up in the cups. It is so comfortable and gives me such a great shape without wires but it does cut into the inside top of my boobs giving me a little quadboob. I think the long line shape is very flattering under clothes, and the vertical seams on the cups help with nipple show through.
I have never found a non-wired bra that gave me such a great shape. The long line band is very snug on the loosest hooks but still fits. The seams on the cups help with nipple show through but does not stop entirely. My new favorite!
