1. Striped Shirt

While Heidi opted for gray-and-navy stripes, we recommend going bolder! The "mod" look is hot right now, so try on this white-and-black version ($22, alloy.com) and see what ya think!

2. Halter Tank

Showing your bra straps isn't cool, but showing your halter straps are! Wear a pony, and flaunt a flirty halter like this one ($22.50, alloy.com) under your fave sweater.

3. Yellow Purse

Yellow isn't mellow! Especially with this brighter version of Heidi's handbag ($29.50, alloy.com). With spring right around the corner, you should snatch one up!

4. Dark Denim

Even with warmer weather, dark denim is still in! Want a pair of jeans like Heidi's? Check this pair ($46.50) from Alloy.

5. Metallic Flip Flops

Forget gold, silver, and bronze! With these fun flip flops ($18, delias.com), metallics come in all colors of the rainbow. We picked these yellow ones, but feel free to mix 'n match!
