Burberry Brit - Oversized Jacket, Size 6, Reddish Brown Colour

Burberry Brit - Oversized Jacket, Size 6, Reddish Brown Colour. There are some white stains on the right sleeve. I'm not sure if the stains can be removed or if it just discolouration of the fabric. But the jacket is otherwise in very good condition and is very well made. Worn only a handful of times. 100% cotton.
