This is a blouson from Double Standard Clothing. I usually wear a size 38, but I chose a 36 for a more compact fit. Those who usually wear a 38 can also wear this comfortably. I've only tried it on, and I don't remember wearing it outside. The size is approximately 38cm for shoulder width, 43cm for body width, and 55cm for length. Please note that these are approximate measurements, so there may be some slight variations. I also have many other Double Standard Clothing and Sov. items for sale!
