Love this bra, it is definitely designed for large, heavy breasted women.  I think the band runs small.  I usually wear a 42G and need a 44G in this brand.  It supports beautifully and is comfortable.  I can wear it all day and don't want to yank it off as soon as I get home.  Of course, not as comfortable as a non-wired, soft bra, but they don't give much support and in my experience, my breasts sag a little lower throughout the day until there is not much lift at all.  As large busted women know,it is so hard to find a bra that is comfortable and also supportive. In my experience, this is one of the best.  And...best of all, the wire lays next to my breast bone all day!  I have never worn an underwire that laid flat.  I always had some degree of the "third boob."  What a wonderful surprise, support without the wire poking out.  Also, I am 5'1" with a short waist and I do not have a problem with the side-boning poking under my arm.  One needs to pull excess breast tissue in front of the boning into the cup to help prevent this.  The side boning needs to lie as flat as possible.  If you have large, heavy breasts, you might be very happy with this one.  Everyone is different, but it works for me.
