I searched it from many sites without luck, and finally scored it from DressVenus, which is another great online store for affordable fashion!
The incredible zipper design and the slim fit offer many ways to style this jacket, a dress under, a vest over, or even a denim overall would all be nice fit!!
It comes with 3 chic colors, check them out here, they are all super cute!
Jacket: Dress Venus (c/o) (worn in size small)
Tank: T by A. Wang (worn in size xs)
