I first bought this bra in Canada for $114.00 just over a yr ago, and, I must admit how happy I was to find it on Amazon.
One cup is made in 5 sections, the under wire is well covered so it doesn't stick in anywhere and it fits perfectly between my breasts the support is fantastic.  I'm a 38I with a slim figure, when I was measured this was the right size and I tell u I tried on a lot of bras.  I purchased a chocolate coloured keira under wire January of this year and @ this time am wearing it on the last hooks, in about 3 months it will stretch a bit, then I'll be using the middle hooks, after 8 months the first row, which I was told would happen...it's nice to be able to loosen the bra when needed during the day.  The bra straps don't hold all the weight of my breasts, this bra is so well made that the weight is properly distributed.  My first keira under wire bra after almost wearing it everyday looks and feels exactly like my new one!!!
The secret is to wash it in cool water by hand and let it drip dry from the under wire, I use a hanger with clips on it.
I have fibromyalgia and chronic pain and I can honestly say this is the best bra I have ever had that doesn't hit any trigger points!!!
