Today I bought a Rick Owens DRKSHDW jacket. (Yay.) It has an interior strap, black cotton about an inch wide and 20 inches long, stretching loosely from underarm to underarm. I've seen straps like it on other Rick Owens jackets too, always on the inside.
I will probably just ignore it, and let it hang down inside of the jacket. But I'm curious to know what it's for and how it's expected to be used. Thanks in advance if you know :-)
