My bra size varies bra to bra. I'm a 30c but as tansy pointed out about last sense - I needed a D in their bras. Some of mine are Bus and if you put them next to my c cup bras they are exactly the same size. I was looking at bras the other day too and the c cups they had were about as big as my frickin head!
a 30C will have the same size cups as a 32B. As I mentioned, the cup size refers to the volume so if you increase the band size by 2" and go down one cup they will be the same.
If they C cups were as big as your head, were they also a bigger back/band size?
you get the opposite when girls don't measure properly and then get double boobs. big shops are useless at bra fittings. you need to be taught how to do it yourself as well. girls don't put their boobs in bras properly
I'm just glad I stick to clothed shooting (though we could extend this to dress sizes as some size 10 models seem to weigh more than I do!)
There are definitely plenty of models who claim to be size 8-10 in denial. Saw a classic on another site last week. A shot of 2 models together, both claimed in their profiles to be a size 8 but one of them was AT LEAST my size!
I'm currently 5 months pregnant and am busting (no pun intended) out of my Debenhams 32A push up bra, however my La Senza balcony 32A bra, that I bought because its really pretty and I had a vain hope it might fit one day, still swamps me.
Different shops, different styles, different fits.
I have never actually been measured. Have always been a bit scared they will give me a raised eyebrow and direct me towards the children's crop top section.
