Personally, I would skip the prom. I would experiment with "dressing up" at a less stressful event. You have to find Your way. Maybe try some different styles until one feels more "right" than the others. For example, the first time I wore makeup was to a big dance. I felt strange and artificial, and I did not enjoy the dance. Play with style and makeup/no makeup in your spare time. ps. Don't let people "rope" you into things. You sound like you have a mind of your own. Trust your thoughts/feelings.

Get some sweats and bedazzle them lol. Screw fancy gender stereotypes wear what makes YOU feel good in.

I can't relate at all because I'm terribly jealous of my daughters getting to get all dressed up for their winter formal and prom. I'm so girly and would love to wear a super fancy dress, get my hair and makeup done....sigh.

But this is about YOU! As the others have said, wear what you like and maybe try to "up" it a little so it's more fancy. I should have looked to see what size city you live in. Hopefully you are in a decent sized school or at least a more progressive one where you can get by with being more funky rather than traditional.

Would love to see what you end up coming up with (hint, hint, hint).

I can relate my daughter does not like dresses either. Why don't you look at nice pant suits. Some of them are nice and not too dressy.

you don't have to dress nice for nice events.
Wear what you want.

Try going naked, that will get everyones attention ?

Dress however you feel comfortable the most beautiful thing a woman can wear is a smile and it's a hell of a lot easier to smile when your comfortable.

I don't like dressing up either. I have had to for a lot of occaisions and I usually feel like another person when I wear a dress. I tried steps and stepping out of my comfort zone slowly Like experiment with a little makeup, try a little nude lipstick. Try a cute pantsuit, wear a dress for an hour, or work up to wearing one for a half a day. Lol! A new haircut is a good way to make a change. Like other's have suggested, look on Pinterest for looks you like. You shouldn't have to anything you don't want to do. Just be you.

Black dressy pants, a classic tunic top & maybe a bit of jewelry is always classic, comfy, & right. Who says you need to wear makeup??? If you feel like it, treat yourself to a cool hair ornament, or chalk in a bit of color! Oh, and sandals or high tops on your feet. And Dance!

I don't think you should even worry about how you're going to dress - if you don't want to go, don't go. You're officially an adult woman and you can do (or not do) whatever the hell you want.

Check the dress code and research outfits that would fit your style.

How about these?
