If you're stuck on what to be for Halloween, here's a smart idea: Why not dress up as your fave little liar? If you can get some gal pals together, you could all go as the fab four, though there's nothing wrong with flying solo as a Pretty Little Liars character, either.

For those who need a bit more inspiration, here are some tips for capturing Spencer (Troian Bellisario)'s put together preppy style.

The sweater: A pretty, preppy cardigan like this simple look from Madewell is the perfect base for creating an authentic Spencer look. Plus, you'll be warm!

The jacket: Spencer always has perfect jackets during fall. Go for something with a traditional cut in neutral colors or plaid, like this DAKS trench.

The pants: Spencer likes clean cuts, and often goes for skinny jeans in dark colors, like this pair from Rag & Bone. With a long enough sweater, leggings could also work, but keep them simple.

The shoes: Try some classy boots — this pair from Lanvin can be inspiration, though the price tag is a bit hefty for a Halloween costume!

The accessories: Like everything else, Spencer keeps her accessories simple. Some nice pearls, gold, or other classic jewelry — like these earrings from Marc Jacobs — and a complimentary scarf (try something like this look from Tommy Hilfiger) should do. And remember, Spence loves her hats! Why not get a cute beret to complete the look?
