What to wear: Tiffany and Derek always travel like the pair that they are, so this costume idea is perfect for couples. For Tiffany's outfit, you'll need a dull green, pink, and white stripped collared shirt, a soft pink blazer, a small pearl necklace, and a hot pink patterned headband.
For Derek, grab a cream coloured wool letterman jacket (bonus points if it's from Stanford), a blue sweater, and a gold watch to complete the look.
