It may be pouring outside, but it was all strappy sandals, hydrangea bouquets, and straw hats at Madewell’s spring 2012 preview this morning. The upcoming collection expands on some of this year’s trends, including loads of stripes, loose knits, polka-dot prints, and pleats. Skirts are still skewing longer — midi- to maxi-length — and cropped trousers in flashy prints replace last season’s neon skinny jeans. This being Madewell, denim and chambray pair with everything, playing off the eye-popping colors and girlish florals. The accessories selection brings an array of pointed-toe flats, colorful straw fedoras, peep-toe wedges, and mini cross-body bags. The collection will start to trickle into stores in February and March. Click ahead for a preview.
