Classic Cardigans

There really isn’t a better match for a silky blouse than a lush cardigan. And Casey knows this – almost all of her outfits include a sweater or cardigan of some sort, usually in a pattern or color that complements her top.

Although cardigans are a favorite of older generations, they can also be youthful and playful, a fact that’s evident in Casey’s looks. To channel Casey, opt for sweaters in fun colors or patterns, and don’t be afraid to mix and match prints. A floral top in light pastels, worn with the Forever 21 striped cardigan below would be an adorable, Casey-esque combination!

Preppy Bottoms

Now that we’ve discussed tops, it’s time to add the last piece of the preppy, sorority girl look – khaki or twill shorts. Unlike the California look of the 90210 girls, Casey favors chinos over denim cut-offs. The trick to making these types of bottoms work is to avoid cuts that are too loose or long, as they tend to look matronly.

For shorts, opt for a pair that hits right above mid-thigh, and that fits you well through your hips and waist. The same trick goes goes for skirts. Whether khaki, plaid or twill, your skirt should be conservative but still youthful.

To achieve Casey’s look, all that’s left to do is tuck your blouse in, add a pretty skinny belt and throw on a cardigan!
