I've never been the most masculine of guys, but I'm pretty secure in my gender identity, however, recently a friend of mine has convinced me to do a cosplay of a certain character that she really is fond of.

That character (for those who don't know, and I apologize for the terminology used here) is a trap from an anime, called Blend S, named Hideri.

Despite those aspects that I cannot change about myself (such as the fact that I'm a foot taller than Hideri) I'm looking for ways to make myself more passably feminine for the sake of this event. Clothes will mostly be skirts and thigh highs, and I'll have to get a wig to compensate for the fact that I don't have nice straight platinum blonde hair, but how can I get my body where it needs to be?

A little bit of additional info for those that might ask, I'm 6'0, 130lbs, not opposed to makeup in the slightest due to my years in theater. I've also got several months worth of time before I need to be ready.

Can anyone offer me some help?

EDIT: For anyone curious, I'll be getting made 4 different outfits for this.
