I'm 65, 14 on a good day , 16 on a bad. I have no idea what my "best features" are. (Not dead?)
I buy clothes entirely on the principle of "wow, that is an amazing dress/ jacket/ coat - does it come in my size" Does it "flatter me" or bring out my "best features" never enters my head. There isn't a week goes by without at least one person telling me what a fabulous dress etc I'm wearing. I guess my "best feature" is a good eye for clothes.
I hope the OP finds this thread useful. It's a wearable, pretty dress.
