Fall fashion essentials under $100

Black Skinnies

A simple pair of skinny jeans is a fall necessity, and black denim is the new favorite. A dark black such as Gap's always skinny ($59.50) that can go with almost anything is a good way to mix up the blue denim regular.

Mini Trench Coat

The trench coat is another classic that is getting a twist this fall. Check out this Urban Renewal mini trench coat ($58) that can be worn open or closed, night and day.

Over-the-Knee boots

Great boots at a great price can be hard to find, especially with this season's trends. The rich brown leather and buckle details in this Style & Co. Rodney boot ($99) will take you more than a few miles in its shoes.

Sequin tank

Sequins don't need to be expensive. A great way to get the look on a budget is with sequins that appear on just the front of an item. Who needs sequins on the back, anyway? For sparkle in the daytime, layer this sequin-front tank from Express ($39.90) with a chunky sweater and flat boots.
