Opposite to conventional Overbust-Corsets corsets with cups (that means: with integrated bra) offer some clear advantages
Thus an integrated Bra offers the advantage, that a large bossom experiences the necessary support, while in case of a small bossom a 'Push-up'-effect can be made possible. Moreover a complete bust-simulation is also realizable.
Understandable, that for this kind of corsets a bespoken taylored corset is necessary, because a large number of size variations are possible.
For the determination of all necessary measurements for a corset with cups you need a special measurement table. Please aks for this sheet.
