some observations i have from looking at young women and not so young women:
a. don't try to dress absurdly younger than yourself. you can always dress older than yourself
b. often women where what is 'fashionable' but it doesn't look good on
them because of their body types. rather than wear what is trendy -fashion is an 'idiot tax' - wear what looks good on you.
c. how you carry yourself is just as important - posture, confidence, grace. I can tell most American women a mile away because 90% walk like men -ungraceful, heavy steps, ...
anyway, I think you should pick a look YOU are comfortable with, find an image/icon admire that both men and women find attractive and echos your complexion and body type.....and try one or two outfits - even if its just going to the store and trying them on....see if you like it....
