LOL yes I know what you mean. That "poke through" is not as much of a concern than the fact I am sagging :( and I do not look good WITHOUT a bra, anymore!
I have begun doing the deer exercise that Zoe has posted and Wombat found and linked to. YET it is not done much for me, thus far...well, In This Time!
I did though last week wear a shirt that kind of held me in and didn't look so sloppy and threw a sweat jacket over it. I was trying to find other options though. Because when I wore the top under a sweater it didn't look near as good.
