just wear a good corset underneath. corsets help enhance a woman's bust line and i'm pretty sure when that comes off for your wedding night your husband would be blown away. it's sexy shapewear unlike some of the other options.
also if you don't opt for that get the shorts because it wont' have you pant lines and that's always a great thing to avoid.
I have no idea where women get those things back home but maybe the others can help you out.
