This may just be the only layer you need this Fall. This transitional jacket is lightweight (while still keeping you warm), has plenty of room for sweaters underneath, has snap closures, and is reversible. We made a neutral side, and a patterned side so you get two completely different jackets in one. It works well with structured pants or your favorite pair of vintage jeans. There's really no wrong way to wear this one. 
size is XS
