Believe it or not, “mermaid” is one of the highest searched Halloween costumes for 2016. And unless you’ve been MIA these past few weeks, you’ve probably noticed your Instagram and Pinterest feeds filling up with all sorts of mermaid makeup ideas. The only problem is half of the stuff out there looks nearly impossible to complete without a few extra hands. While most Halloween makeup tutorials require some skill, it is possible to do it yourself. Mermaid divinity right this way.
