Color: Blue Sleeve Length: Long Sleeve Pattern: Solid Collar: Stand Collar Season: Spring, Summer, Autumn Size 2 (Shoulder width 45cm, Pit to pit 51cm, Back length 69cm) This is Ethosens. It looks like a collarless design from the front, but it also looks like a stand collar from the back. There is some wear and tear, so I am selling it at this price, but I think it is still in a condition where you can wear it fashionably. I will fold it up small and ship it.
