Long or short, slip dresses are a handy AF wardrobe addition. I found all of these in charity shops and on Depop – the red one is from one of my fave American Depop stores @trollfunk.
It’s hard to find charity shops that deal in nightwear and (unworn) lingerie, but once you do, they are a hot spot for sourcing slips that work really well as dresses or tucked into jeans.
