Lauren Conrad showcased her simple, sophisticated style at the opening of the Dolce & Gabbana flagship on Robertson Boulevard in LA. Her frock – with its adorable bubble hem detail – is totally holiday party worthy. And we love how she added a 20's touch with the cute bow in her long, wavy locks.

Take note from Lauren – no dress is too short to wear for a holiday fete. Even the shortest of skirts can be modified by adding opaque black tights. You'll feel covered up but your gams will still look a mile long. Keeping the shoe the same color as the tights continues the leggy elongation. You can also always count on Lauren for the last in nail trends too - check out her gunmetal nails.
