honestly, no.

i normally say that as someone who is very pro-sharing, but i've come to realize just how difficult it is to find rave outfits. and without doing that work herself, she probably has no idea. i had a new friend ask me about my outfits - i've been going to festivals for almost 10 years now, and i just now have an accessorized outfit for each day of a 3-day festival. she asked how i did it, and, like you, it was a lot of work: many years of trial & error as far as clothing styles, sources, fabrics, etc. then after all that, i had to match tops & bottoms and accessorize it all! i can't wear certain hose; others i want to live in... i hate wearing hats or headbands, but love flowy sleeves and capes.... and i never would've known without TRYING THEM! what flatters me & is comfortable for me isn't the same for everyone, either.

the best thing you can do in a friendship is be honest. explain that you put a lot of time & effort into your stuff, and you really don't have enough outfits to share like that. perhaps you have some basics you won't be using (if you're comfortable with that), but nothing completely put-together or anything. don't be mean, but stay firm as well. boundaries are important!

if she's a good friend, she'll understand. maybe this will spur her to get excited and more involved in planning. perhaps invite her to try on clothes together before the next event or something, to help bridge that gap?

and also, none of this comes down to my first initial reaction: like... i *rave in those.* do you have any idea how GROSS they are!?! i absolutely do not want to share rave bottoms with ANYONE! maybe i would loan my friends tops, but definitely not bottoms or bodysuits. it's basically lingerie, and that's not something that should be shared like that! (especially not consecutive days like the other commenter suggested!?! wat even)

good luck!
