Being self conscious about dressing my age, for our vacation coming up...

All of my life I loved fashion, dressing a little smexy, yet conservative, that little black dress, fun flirty dresses, and ruffles and lace, but that was back in my 20's and 30's, now I am in my 40's and I look my age sooo for our upcoming vacation, I'm conscious of trying to dress my age and yet look stunning, by having my own style, that compliments my body type, and yet doesn't make me look too unnatural. So when I go shopping I'm going to incorperate that thought logic into my decisions. In hopes to look good even at my age!
