While I like a nice bangle bracelet or a long charm-laden necklace as much as the next girl, my go-to accessory is the belt, because adding one — or switching them up — can change an entire outfit. The only problem is that belts that work with lower-slung pants are way too long to wear with dresses or over cardigans. J.Crew often styles its catalog models with the end of their belts tucked in, and while we like the casual coolness of this, Kristen Bell took this technique one step further by turning a too-long belt into a decorative knot in the front. To tuck yours the way Kristen did, take the end of your belt and slip it under, then over the belt, pulling it through the loop you created. Voilà!
