Tying a scarf can be a challenge. There are tutorials all over the web on how to wear them. You can do a slip knot, a reverse knot, a reverse wrap-a-round, a shoulder tie… or you can just throw on Marc by Marc Jacobs Pippa Scarf T-Shirt ($78). True, it won’t keep you warm, but with the high temperatures out west, warmth is the last thing I’m worried about.
