Fashion emergency - self conscious

I'm having a total girl moment this morning. I'm wearing one of my new dresses and I'm SO self conscious about myself in it. I keep freaking out and really would love to go change. There's nothing wrong with it, it fits correctly, it's just clingy. I asked 2 strangers at Lane Bryant when I bought it, and my mother & hubby after I got home. They all agree it looks nice. I'm just still not used to wearing form fitting outfits, I've been wearing nothing but big boxy stuff for the past 3 years. Ugh...
