In warm-weather's most happening hue (canary yellow, oh yes), Jenna is definitely not your typical crop top. Preppy, pretty, and social-media savvy, look for Waspy stripes, a dusting of exquisite white lace, a longer length that exposes just a sliver of stomach, sleeves that flatter any arm, and — to give Jenna a more dressy vibe — an interesting center front snap closure. Team it up with the matching Liana skirt to get really sunny.
