Our Lulu Noir Merry Widow is sized by bra size.
Bra sizes roughly co-ordinate with the following dress sizes:
32" - WKD dress size 6
34" - WKD dress size 8
36" - WKD dress size 10
38" - WKD dress size 12
If your bra size does not match your body size you might like to experiment a little and delve into the mysterious world of bra cup grading.
A bra cup size 38B will be the same as a 36C, 34D, 32DD. Hence if you are normally a bra size 34D but a small dress size 6 you might want to try the 32DD corselette which will have the same cup size as a 34D, but will be smaller around the body.
This grading works across all bra sizes so:
Cup size 32F = 34E, 36DD, 38D, and so on.
