TG, I want to thank you for the link to Truth is Beauty. That blogger certainly has several interesting points. One of them is, as already mentioned by you, that you should dress for your face, not your body. This point appeals to me, as I have never felt that the recommendations for "hourglass," "pear" or whatever are really relevant to me.
(In my case, the closets description is a slim 8 shape, which is a body shape that few other people than Imogen Lamport offer advice for. She also adresses some of my other body features like "long rise" and "long decolletage," and I have found her tips helpful and can warmly recommend her blog, insideoutstyleblog.com, for tips on such issues.)
However, up through the years, I have experienced that when I just dress as a mix of Classic and Gamine (without thinking too much of my body shape and body features), I get lots of compliments AND feel this style is very me.
Another fact, related to the recommendation of "dress for your face," is that your hair style is an important part of your style. This, too, is something I have experienced for decades. Whenever my hair grows too long, I "loose" a part of my Gamine style. OTOH, whenever my hair is cut (relatively) short, I get loads of compliments and feel much more like "me."
To those of you who are discovering your style or are contemplating changing your style: I strongly recommend taking your hairstyle into consideration, as your hair is a key element of your personal look. And do dress your (new) style when you go to your hairdresser! That will make it easier for him or her to "see" you and to help you get a hairstyle which matches your general style.
