Lets leave the humor aside & get to serious business. So what actually the Bra sizes are meant? Bra styles explained:
Underwired Bra: Best For: "Everyone! - most women prefer underwiring in both their everyday and evening bras as it gives support and lift. The only time this is a less suitable choice is if a woman is particularly irritated by underwiring or has very small breasts in which case underwiring is not necessarily needed."
Triangle Bra: "Best For: Smaller busts not requiring as much support, pert breasts, a casual look - day to day."
Soft Cup Bra: "Best for: Small busts, bedroom wear."
Push Up Bra: Best for: Any size up to a D or DD cup.
Padded Bra: "Best for: Any size up to a D or DD cup."
Half Cup Bra: "Best for: Smaller busts requiring less support, a sexy evening look."
Full Cup Bra: "Best for: Bigger busts requiring great support and fit."
Hope this helps least a bit.
