Is it normal 3 bra's are the same size but, don't measure the same?
I noticed that when I purchased my 30D bra online (have trouble finding that size in stores) It was was bigger than my other 2 30D bra's.
All three are made by different brands.
One is by Gossard (it has the smallest fit) the back only measures 21 inches when laying flat. The inside of the cup measures 7 inches from side to side, the height of the bra is 4 inches.
Another is by Curvy Kate (it has the biggest fit) the back measures 24 inches when laying flat. The inside of the cup measures 7 1/2 inches from side to side, the height of the bra is 5 1/2 inches.
Another is by Marks & Spencer, the back measures 24 inches when laying flat. The inside of the cup is 6 1/2 inches from side to side, the height of the bra is 5 inches.
I know I am a 30D but, the only bra that fits is the one by Marks and Spencer. The Gossard bra's cups fit but, the underwire hurts my ribcage after a while and the band seems a bit too small also. The Curvy Kate bra is big in the cup area although the band fits perfectly. So does this mean I'd be a 30C in Curvy Kate bra sizes and maybe a 32D in Gossard? And why don't all bra sizes have the same fit?
