What's the difference between a 36A and 34A in bras?!

A 36 will have more room around the bust line (under the boob / the rib cage) than a 34. Essentially, in cup size, yes a 34B, is about the same as a 36A, but a 36 will be bigger "around".

I wear both a 34C and a 36B.Health Question & Answer

Cup size is the same, it has to do with the area under your breasts. Take a measuring tape and go all the way around your body. If it's 35.5 go up to a 36, if it's under 34.5 then the smallest you can go is 34. Go to Victoria's Secret, you can try them on. Or if you want go to JC-Penny and get fitted, that way you are not wearing something to big that will ride up or too small which will pinch.Health Question & Answer

if the cup is B then the actually boob is bigger and the boob is like 2 in. bigger than the rib cage. if its is A the boob is in bigger than the rib cage. so technically B is bigger.

36A and 34A diff. the ribcage of the 36A is bigger making the person look bigger as well.
