Most Helpful Girl
Not really. Personally, my clothes generally just reflect my mood when I was getting ready.
I don't think the way you dress is particularly indicative of who you are. Maybe the more superficial things, though. Your taste in music, some hobbies, etc. But even then, I don't think it's very accurate.
For example, there was a girl in my classes who was covered in tats and piercings and dressed kinda emo-ish. Total babe, imo. She was a stripper. Read gothic novels. Bisexual. All seems stereotypical so far? But she was also the most articulate person I have ever met. She was doing a degree in women's studies. Point: some things might be representative, but there is always more to people than meets the eye.
Assuming otherwise breeds ignorance and short sightedness, imo.
