This is a cosplay of the PE uniform from Boku no Hero Academia.
I wore it twice but years ago, so it's been sitting in my closet since then.
Still in good condition and it's a good outfit.
Measurements are:
Waist - 27 unstretched to about 32 stretched
Inseam - 30
Length - about 40
Bust - 47
Shirt length - about 24
