is this a BBL jacket?

I am 5’8, 36 bust, 145 lbs. usually wear a medium and prefer tight fitted. M or L for size? Thank you.

Specifically looking for a nylon/spandex blend. Do all the colors come in nylon? description sates fabric varies on colors- confusing

Can anyone describe the diff between scarlet dusk and chocolate burgundy?
