Slip dress over vintage jeans? Oh yes. You guys know I live in these jeans, but I also love living in vintage slip dresses so sometimes when the mood strikes, I go with both. To pull off the look, you have to get proportions right. I’m an expert at this given I’m on the shorter side. If you’re going for a long slip dress, then opt for jeans that hit right at the ankle (see this post here). If there’s a slit on the maxi sip dress, even better. For shorter or mini slip dresses, you have some more options. I always like ankle crop length, but you can also opt for wide leg or flares that cover the shoes.
