I'm definitely an outlier -- in several ways. For example, I come from a family of musicians, but was the only woodwind player among lots of brass. I'm also the only serious singer, which is more significant, since I process music quite differently, both emotionally and neurologically. As for fashion, I do wear similar colors to my mother, and even my daughter, who is Chinese, favors jewel tones, albeit more muted ones touched with brown and green.
I think I value individuality in dress, without pushing environmental boundaries too far, so I see the individual choices in those around me. In my nuclear family, every one has their own style:
My DH is the button down with jeans sort: I have worked to lower the rise and change the rinse of his jeans. He's very practical, but looks great in a suit: a perfect 38/40, with broad shoulders, long legs and a waist size that's only one inch larger than it was 30 years ago.
DS is a golden retriever puppy: all legs (a 28/34), long sandy curls (yes, this is my son), and an endless supply of school swab (Both his high school and Purdue Univ., where he wants to major in Engineering). Girls are starting to notice his goofy self. I still have to count his underwear in the wash and remind him that there is an expected rotation.
DD has her own distinct style. She's not loving high school, so I can read how she's feeling by what she chooses to wear: no makeup, a sport tee, skinnies and tennies means she feeling down, while jewelry, makeup, cute hair and top, skinnies and booties or sandals means that she's doing better. She is casual, but feminine. A bit of boho, but not too. I can see an item in a store and know whether or not it's "her."
