It's probably all due to the hats, but these outfits seem like something flight attendants working for Yarn Yuck Airlines might wear...
Oh me, oh my...
The slit sleeves on the model to the right!
That long mesh apron on the model to the left!
Those stirrup things worn over the boots!
(At least the top part on the left piece is pretty cute. If I could get that as just a shirt (no skirt attached), I'd wear it.)
