Little houses on the hillside little houses made of ticky tack and they look just the same. C'mon people if we wanted to blend in just wear what you wear now, Part of the fun is dressing up and being pretty and I love to be noticed.
The OP "rules" may work for posing and static photos but as Karren indicated we don't walk around sticking our butts out and sucking our stomachs in. Neither do GG's! And they don't all put their hand on their hips and bend at the waist or point one foot in front of the other. They don't walk like catwalk models.
There was a thread not long ago asking why CD's tend to pose in suggestive ways...this thread answers that question. Put your right foot in put your right foot out ...stick out that chest soldier, stand up straight shoulders slumped (because if you throw out your shoulders you look masculine) but do stick out your chest! Wait slump your shoulders and sick out your chest...doesn't that make you look like the crones in every fairytale? Girls don't put their hand on their hips with the fingers in front was one of the first things I was told in how to present...I rarely see women with their fingers in the small of their back unless they have a backache (from slumping and sticking out their chests at the same time no doubt).
Fashion is...well fashion. It is the statement a person makes by donning clothing that they like. If you follow someone else's "fashion advice" it isn't your fashion it is theirs and you are emulating it.
So, here is the deal (as I see it). Be yourself, have fun, wear what you like (within laws and local regulations), stick out that chest and be proud. If you want to blend wear drab clothes that no one will notice, but trust me when you start trying to follow the "rules" to fit in you will stick out.
