Mummettes...wardrobe malfunction?

As little as possible. I usually opt for a nice tight (i.e. makes the ass look great) pair of jeans, capris, etc (depends on weather), and then something low cut. If you got them, show the cleavage. It's what mummettes are known for.

I try to accent my best features. So my smallest shorts, mini-skirts...whatever shows off my legs and butt. Frankly you could wear nothing and you'd be a hit!

Jeans and a t-shirt.

I try to combine comfort and style when possible. Since I'm most likely going to be in said outfit all day, traveling in it, standing out in the weather in it and then dancing my ass off in it, I want something that isn't going to be a pain in the ass to wear. Not always possible but most of the time I can coordinate to accommodate. I'm not sure how the girls wear the tiny heels for any length of time...perhaps it's a youth thing lol. I usually wear comfy shoes at least. Most places, like the Bird, no one is going to be able to even see your feet anyway ;-)

Red, this is what I wear with either jeans or capris.

It really depends my mood what I wear to a show. Last year I wore a lot of dresses. This year been a mixture of nice shirts, leggings and jeans. I do enjoy looking nice and getting dressed up.

First of all, Red, you look young enough to pull off any of the mentioned outfits with class and style.
I would, however, caution against Phunky's recommendation of 'nothing at all'. . . .

Above all be comfy. If you have comfy dressy shoes, go for it.
But remember you'll be jumping around in those shoes for 2 solid hours.

My go-to outfit would be dressy jeans and a sparkly, trendy top,
or dressy jeans and an HCTM t-shirt.

And at my age, I show as little boobage as possible, out of consideration for others.

Here's a suggestion for your first show. Wear Jeans, really comfortable shoes (really, trust me on this one), and a top you can fold up and store in a jacket pocket, etc. When you arrive, find the merch table and buy something that looks good and fits your budget. Go into the ladies room and put it on.

Now, after the show, you're ready to have your top signed wherever you feel comfortable. You can even have the Mummies name your boobies, shoulders or waist. The sky is the limit!!

Edit: The guys will be just as nasty or nice as you like them to be. They really will take your lead for autographs, pics, etc
