There's a reason why searching the tag #DeerMakeup on Instagram will populate over 35,000 images: The trendy Halloween costume is as easy as it is cute. In fact, as complex as many deer beauty looks may seem, at its core, it only really requires the products already in your makeup bag — like bronzer, blush, foundation, and black eyeliner — plus some white face paint. Even so, there are plenty of ways to put a creative spin on this go-to costume.
