6 fashion essentials

Investing in quality, timeless basics gives your wardrobe a solid foundation. Here, Jessica Alba's must-haves

A denim jacket

Some years it's out, but it always comes back. I like it pretty shrunken and fitted to wear over flowing dresses and skirts. (My fave is by Elizabeth and James.) You can also never go wrong with a black leather moto jacket—chic!

A sharp coat

So worth the investment—your outerwear is all people see half the year! Look for quality stitching, heavy buttons, and a nice lining—signs that your coat will last. This is also a place to go vintage, because then you know it has already lasted for decades. Plus, retro coats are just adorable.

The little black dress

A go-to for a date or night out with friends. Azzedine Alaia or Dolce & Gabbana if you're going there (Diane von Furstenberg also has beautiful options): J.Crew or Target if you're not.

Neutral t-shirts or tanks

Figure out a neckline and sleeve length that work with your body. Then buy tons in white, gray, black, and tan to layer under everything. I love C&C California, LNA, and Cheap Monday—and long and lean tanks from Target hold their shape for under 10 bucks a pop.

Your perfect jeans

Avoid crazy stitching and bedazzling on the back pockets. A little stretch is nice because it hugs your curves. Right now I'm loving slim boyfriend jeans: They're so comfy and you can wear them out with heels. You can't go wrong with Levi's; the Gap is great too. For premium denim, I love Sevens, J Brand, and Earnest Sewn.

A fitted blazer

Navy or black blazers are an easy way to look stylish. Pair with an A-line dress, maxi skirt and tank, or T-shirt and jeans. I love Celine, Narciso Rodriguez, and Givenchy; for less expensive options, check Topshop, H&M, J. Crew, and the boys' section at Brooks Brothers.
