I was just reading some random article about fashion advice for middle aged women, and it occurred to me that much of the standard advice -- don't wear crop tops or micro mini skirts, avoid things that are too tight and revealing, etc. -- is much the same as the advice for us fat folks. In that sense I don't think I have to worry about looking age appropriate because many of the styles that are prone to being read as juvenile are not things that I would wear regardless of age, because I would not feel that they flattered me in the first place.
