When we're little, our moms dress us. Any way they want. They have unfettered freedom to choose our clothes, regardless of how hideous or cute the items are.
As we grow up, however, we reach a point where we rebel. No! I don't wanna wear this!
That moment occurs at different ages for us. Some kids meekly defer to their moms, some robustly defy them. For many, it's when we start to care more about fitting in with our friends that we reject our mothers' choice of unpopular clothes. We want to wear the styles and brands our friends are wearing so we can gain their approval or, at least, not be ostracized.
For girls, I imagine this is especially important since clothes themselves are so vital. On one hand, I think it'd be great to have an adult female who can advise and guide you into fashion; on the other, the fact that she's a generation older means her taste is probably old-fashioned and she's not clued into what the kids are wearing today.
How was it with you? When did you start wanting to wear different clothes than those your mother picked out for you? Was that an easy or hard conflict? Was your mother's taste outmoded or acceptable to you? Finally, did you ever reconcile this conflict with your mom as you matured?
My mom chose clothes no cool kid would be caught dead in. They were what old people wore and, even worse, they were cheap. My mom shopped at bargain-basement discount stores and her purchases embarrassed me in front of my friends. I struggled with her over this for years. At the same time, I recognized that my mother loved me and was doing her best with no fashion-sense and little money. That realization made our conflict harder 'cause I didn't want to upset her by arguing. I just didn't want to wear her awful clothes.
This may seem funny to you now, but imagine being dressed up like a little immigrant in a suit and a hat. I hated those clothes.
Don't believe me? Here's a picture of my brother and me. He's the little guy on the bottom left; I'm the slightly-bigger little guy on the bottom right. We're surrounded by my two aunts and uncle.
Oh, and I did I mention my parents made me play the accordion? The most uncool instrument in the entire world? :)
