[Marvel] New Costume for a New Speedster!

Hello Reddit,

My hero name is Speeding Betty, and I've been established in Downriver Detroit for the better part of three months, and I think it's time to go legit! I've clocked up to 300 mph and could probably go faster, but what my dad calls my Speed Aura completely wrecks my clothes once I pass 270ish. My dad is okay with me caping since the Aura cushions my body from physical damage and I get a healing factor, haven't really tested that, because ouch. But the big big BIG hangup right now is the costume. I want it to cut down drag, be able to keep up with me and be resistant to some of the supers in my area. (Fire, Frost, Thunder, guy with a sword) Dad wants it to be in his budget, since he's trying to be supportive, but also wants it to be "modest," which means whatever he wants it to mean after a tangent on the X-Men and showing less skin than a Norse God. Anyway, what do you guys recommend?

Talk to Reed Richards.

He specializes in unstable molecules costumes that should be able to keep up with anything you can throw at them. If your super speed turns out to be the one thing that the unstable molecule suit can't handle, then that's actually good news, because now you've just given Richards a novel problem to solve. He'll likely spend an afternoon redeveloping materials science from the ground up as an intellectual exercise, and you'll wind up with a nice super suit.
