Red Velvet Smoking Jacket With Yellow Accents

I purchased this classic-style red velvet smoking jacket with yellow accents (at the collar, cuffs and pockets) for a Halloween costume to dress up like Claude Rains in the 1933 movie The Invisible Man. I received many compliments, but I no longer need the jacket.
It has two functional pockets on the outside of the jacket and two pockets inside as well.
I usually wear a US men's size Medium, and this jacket fit okay. It's probably right on the line between fitting guys who wear Medium and Small. If you wear Large then this will be too tight. I don't know how to properly measure garments, but while wearing the jacket the shoulders seem to be about 19.5 inches from tip to tip. The sleeves are 25 inches when measured from the top of the shoulder, and 17.5 when measured from the armpit. It seems to fit a chest circumference of around 40-41 inches. The length from top to bottom is about 30.5 inches.
