Cricket - okay I concede - not compared to you!
I guess I was thinking of Angie and Taylor and Theresa when I said my ribcage was large - especially Theresa since we are the same height and about the same weight (as well as in the same country!)
I haven't had a bra fitting yet because I chickened out (!) and also because my toddler is still breastfeeding and she yanks up the band (we are as of last week down to only 2 feeds a day from heaps every day so making a bit of progress there).
I only times I have been fitted were at 15 with a 32A and when pregnant with a 32C maternity bra. Have also worn 34A. My recent maternity bras were B cup and are way to big for me.
I can relate to Marianne and Wilson with having things zips sticking at the rib cage!
Part of the challenge I face is that being long waisted as well means often the waist of a garment is actually on my ribs.
I don't find fit a major issue, but do often find things fit at my (square) shoulders) are tight around the rib cage and then loose.
Also so far as figure flattery goes, I have to be pretty careful about empire seams (like Marianne) as this is a broad place.
