Lorelei is right, I started a 32a had 380’s (mario said I would be a d with that size), but iv ended up a ff, but I look a d, which is what I wanted. Other girls have been told bigger sizes from a 32a will make them a d, and some measure smaller then me po, as we are all different, and only a surgeon can give you the options on sizes (some girls have shed many tears after settling on an implant size and being offered much much smaller then they thought)
Implants measure bigger then they look, as they project more, even low profile ones. Which is why loads of us end up measuring so big. It’s best asking your surgeon a size or shape 
Hope this helps xx
