colorful dresses and makeup mishaps

I had yet another dream where I was picking out clothes and trying to get ready. I was at my parents' house, and I was supposed to be participating somehow with my sister in the church service at my parents' church*. I guess I hadn't packed any appropriate clothing, because I was looking through the closet in my sister's old room. There was a huge selection of dresses, so huge that they were stored on one of those rotating racks like at a drycleaner's. I could tell that most of the clothes had been found at thrift stores. They were all really interesting, with a lot of prints and unusual color combinations. Some of them were overtly "ethnic" and others not, but they all managed to be unusual while still being very wearable and not too weird or cutesy. I was really impressed that she had amassed such a huge collection of interesting clothes, and ended up spending too much time browsing. I finally settled on a black dress** and realized I hadn't left much time for the rest of my preparations.

At that point I looked in the mirror and realized that I looked better than I would have thought given my lack of cosmetics, and also that I was a very young-looking Asian girl with bangs. Apparently my sister was also Asian, and she looked much older and more sophisticated. I worried that, especially if I didn't have time for much cosmetic work, people would think we were mother and daughter.

I guess I had time to start on the cosmetic work, because the last thing I remember was putting a mascara wand back into a bottle of makeup because I was in a hurry and being frustrated that I had probably messed up both products.

I think it's weird that I have these clothing/preparation dreams so often. I love the clothing parts and wish I could remember the details when I wake up; the preparation parts I could do without, though. I wish I could come up with an interpretation for them that doesn't point to unhealthy appearance anxiety.

*That reminds me that I periodically have dreams where I'm supposed to play the piano for their church (something that happened a lot growing up) but haven't prepared anything and am trying to figure out how to muddle through. These dreams feature a weird combination of performance anxiety and hubristic overconfidence that I'll just be able to improvise something baroque-y.
**Why did I choose something black, with all the beautiful colored and printed options?
