10 Halloween Costumes to Beat the Fall Heat This October

When planning and finalizing your Halloween costume, it's important to keep the temperature in mind. The spooky holiday lands on October 31, which is technically considered fall, but oftentimes, on this day, there can either already be snow on the ground, or it can be quite warm, which means you either need to bundle up or you need to wear something lightweight and airy. Need some ideas for the latter? Well, you've come to the right place, because today we're rounding up some of the best (and easiest) hot-weather Halloween costumes that will keep you looking and feeling cool on October 31.

The formula for the perfect costume to beat the fall heat is simple—stick with your lightweight, summery pieces (think dresses, shorts, or skirts) and avoid too many layers. Some getups we have in mind that are both fashion-forward and cool(ing)? Easy. Go as a trendy tourist and rock a fun tropical print top and cargo shorts. Or go as bombshell icon Marilyn Monroe, which only really requires one signature piece—a white halter-neck dress. Ready to see the rest of our edit? Then read on for 10 hot-weather costumes to try.
