I forgot the jelly/lotion part. Great for not staining your skin. Good tip.

I use a wig cap which is essentially just a nylon hat and stuff all my hair underneath. I keep my hair short-ish so it's easier. I pin that and the wig down with regular bobby pins. If it's a lace front, meant to look like a natural hairline, I use wig glue and foundation to hide the lace. A good wig is one that fits nicely already and all the extra steps just help keep it down.

Sometimes I just toss a wig on under a winter hat without all that if I feel like having long, outrageous pink hair on a cold day.
