Midi Overalls Dress from Japanese Boutique

I love this dress so much! I bought it when I was in Japan, hoping I'd lose the weight... I didn't and now it's yours! This style is super "in" right now - I'm so sad to let it go!! This dress has pockets, functioning snap buttons, and adorable strap adjusters. It is a deep navy blue jean fabric. The tag says the size is "F" which I think is for female? Haha. But it fits a size small. Never been worn (except when I had my roommate model for this)!!
