I did a little research on what’s in this fall, and chances are these top 10 essentials are already in your closet.

1)  a Plain White Tee

It goes with everything and makes it all a lot better. You’ll wear yours under  a blazer, tucked into a high-waist skirt or with cut offs.

J. Crew Perfect-Fit Tape Boatneck Tee, $15,  jcrew.com

2) Black Leggings

Whether you wear them as pants with an oversize sweater, under billowy dresses for extra coverage, or kicking around running errands, black leggings are a must- have.  Mixit Solid Leggings, $15, jcpenney.com

3) Ballet Flats

More chic than sneakers and comfier than heels, ballet flats are the best of  both worlds.  I personally love them paired with slim cut pants.  Charlotte Russe Studded Bow Flats, $13, charlotterusse.com

4) a Skin-Tone-Matching Cami

A skin-tone-matching cami is about as basic as it gets.  Layer it under sheer blouses or  dresses to avoid overexposure.  Wacoal Camisole, $25, bloomingdales.com

5) a Black  Cardigan

Black cardigans are timeless and effortlessly chic. Keep one under your desk for aggressive air-conditioning, or wear it over a sexy dress on a night out for a hint of sexy librarian.  Button-front stretch cardi, $25, oldnavy.com

6) Classic Pumps

Stock your closet with a great basic, goes-with-everything pair of heels, and I promise you’ll wear them to death. Bandolino Shoes Eladia Platform Pumps, $55, macys.com

 7) Dark Denim

Flattering and timeless, a great pair of dark jeans can do wonders for any  woman’s wardrobe.

8) a White Blouse

Nothing says “I have my act together” like a crisp white shirt.

9) a Little Black  Dress

When you find the perfect LBD…buy two!!  Dress it up with your pumps or down with your equally important ballet flats.  Forever 21 V-Neck Sheath Dress, $18, forever21.com

10) Classic Black  Pants

On the weekend, they’re rock ‘n’ roll cool and during the week, they’re totally office-chic. Black pants are also slimming – as if you need  another reason to pick up a pair.
