Last year I tried the "bra intervention" method of measuring, and after years of wearing a 36G found I was more of a 34H or HH. 32J at a push.
So I bought a multitude of different makes of bras in various sizes, shapes and types, and spent a bloody fortune. 50% went back as they didn't fit me at all. Some fit but the wires dug in at the front or under the arms, or the side boning was uncomfortable. Some fit but the straps constantly slip.
After 12 months of trial and error I still have no bras that fit reliably, so I kept the ones that felt most comfortable and bought some clips to hold the bloody straps up, and binned the rest.
I did finally find some nice 2-packs in great colours on Simply Be - the 34H was a touch too small in the cup, so I ordered 6 of the poxy things in the sale, in a 34J. Cup is too big, and it doesn't come in an HH or a 32K.
Bravissimo is expensive, Brastop is alright but I haven't had much luck with the fit really, Simply Be don't have any value packs in my size and I just want some inexpensive bras that are vaguely the right fit!
Any ideas? My bosoms crate a massive shelf about 4 inches wider than my actual ribcage. So fed up with looking so wide.
