I'm not a huge fan of wigs and have never worn one before this but they're great for when you want to go under the radar. Scarves are really easy to tie - there's complicated designs but I've kept with the simple. Using a long rectangle (it has to be wide enough to cover your head)...start by centring it across the front covering a little of your forehead. Take the sides down and tie (half knot) at the back of your head then bring the ends back around to the front, twisting them as you do it. Tie again over your forehead then, still twisting, take the ends back and tuck them under the first twisted parts. Or you can tie it slightly lopsided and either tuck the final ends so you have more of a bulge on one side, or let them hang free.
