The trickiest thing about packing — and dressing — like an Outside Lands pro is taking into account the unpredictable nature of San Francisco's temperamental climes. Although this weekend's festival forecast calls for mild and sunny weather, you can never be too prepared for the early evening fog, overcast skies above Golden Gate Park, and blustery offshore breezes. Thus, we've compiled a foolproof list of concert-ready pieces for your perusal, ranging from a cashmere poncho and a lightweight military-inspired anorak to go-with-everything jeans, vintage soft tees, and one silky floral shiftdress. Plan on wearing cozier layers and form-flattering denim in place of your more polished wares — chances are, you'll be on your feet much of the day, so functionality will certainly play a huge role in this styling equation. It's also worth noting that these transitional items will have a longer lease on closet space. Think of these picks as not only worthy Outside Lands purchases, but solid Fall investments too. Here are the 14 must haves to pack, shop, and live in this weekend and through the autumnal months.
