Elila Response: Thank you for your feedback. The back of a bra has 80% of the support and the Elila sizing is based off on getting your band measurement by wrapping a tape measure under your armpits and around your chest just above your bust. If you get an odd number round up. For the cup wrap the tape measure around your back so it comes around the fullest part of your bust, be sure the tape measure is at the same height both at the front and the back Subtract that number to get your cup size in inches and convert. 1 =A, 2= B etc.. Elila cup sizing is the alphabet so no double letters needed. Hope this helps!
