LOL - I'm with ya 100% on this one girl!!
I have the SAME exact problem and can almost never wear button down shirts because there is always an opening between the buttons and well, people get a pretty good view if you want to know the truth
So I hardly EVER wear those because of that reason
Big boobs are indeed SO frustrating! I've told my husband on several occasions that I want a REDUCTION!
Anyone can have mine! FREE OF CHARGE! I hate 'em! LOL!
