Package includes Bra and Panties.
You need to choose the band size according to Under bust (this is where the bra straps hold bra in place)
Band Size is the two numbers in front of letter.
For example if your underbust is 87cm you need to choose size 85(A-E). The letter represents the cup size. I would recommend bigger cup. Like C. This way you can fill the bra cups with something to make you look you have actual breast.
