J.Crew’s youthful spring 2010 collection, which showed on Wednesday night at the company’s offices, was a breath of fresh air. Models lounged and chatted on a wood-planked stage in a mix of perfectly styled outfits, rosy cheeks, and slightly messy updos. Fatigue army jackets toughened up floaty chiffon tops and sparkly sequin miniskirts, while hints of neon added color to a mostly neutral palette. The accessories won our hearts as well, from sparkly, feminine jewelry to boyish, flat leather Oxfords and suede desert boots. The easy, pretty looks, despite endless layering, showed lots of leg, keeping in line with the season’s short lengths. Another reason to look forward to 2010.
