Strapless/Big boobs war

Megan
Fiancé and I are getting married next year. I have a large bust but also pretty petite wearing a size 3 in pants. MOB and I think I will be fine, MOH thinks I'll be pulling and tugging on it all day/night. It has a corset back and I'll get cups sewn into it.. Will this be enough or should I reconsider another style. I'm in love with this strapless though :/
