The white rabbit

Classic tales like Alice in Wonderland can sometimes make the best last-minute, yet still easily-recognizable adult costume ideas. Take this classy version by Dana MacDonald: “It was actually quite simple to do! I tried to do my own spin on it to still make it look like a cute outfit…for the face I used eyeliner for the whiskers and lip liner for the nose.” Post-COVID life will be quite different, but you can still celebrate Halloween in fun ways!
