I discovered a Transfem Secret Technique today, and I'm gonna share it with you.
Wish you had wide, bodacious hips? Get yourself a (longline, probably) corset with hip gores, the modifications a corset needs for very hippy ladies. Put it on. Then, put a midi or miniskirt or dress on overtop. Pleated works best, but anything that's not bodycon works.
Again, pleated works best, but check that out! I have in no way earned those hips.
