Jitterbuggin is based in Portland, Oregon and makes some really fabulous reproduction vintage clothing.
The Bybee dress has sleeves, so works well for both Summer and Autumn, and that green skirt is wonderfully autumnal. There is elastic in the shoulders and cuffs, so on warmer days you can wear it off the shoulder.
I really love the high structured waist band on this as a lot of “peasant style” dresses are very billowy round the torso, which often isn’t very flattering, especially if you have a larger bust! The high flat waist on this creates more definition between the billowy top and billowy skirt.
