/cgl/ - Cosplay & EGL

With no current sewing thread to go off of, I'll post here. I'm looking for an underbust corset pattern and I can't seem to find a decent one anywhere for the life of me that comes with some kind of instruction (I've never made a corset before so instructions are appreciated.)

Do you have any recommendation? Long or short doesn't so much matter as long as it's a true underbust and not a waist cincher.
