The easiest way to spot a pair of mom jeans is to look at the fit of the waist. The style is almost always overly high-waisted to accentuate the butt and has a straight leg at the bottom (via Types of Jeans Fits). It's your classic '90s-sitcom-mom style, and it's making a comeback. Think light wash, no chance of falling down, and easy to wear with boots and sneakers. Celebrities like Kim Kardashian and Julianne Hough rock this silhouette often (via Marie Claire).

This style is super popular right now, but the name of the jeans actually started as a joke. The term "mom jeans" comes from an SNL skit (via Pop Sugar). The skit shows Tina Fey and Amy Poehler in high-waisted jeans, mocking the style. "Mom jeans fit mom just the way she likes it," the fake commercial says. "She'll love the 9-inch zipper and casual front pleats." 

While the snippet might have been mocking the style when it came out, the cut was iconic enough to stick around. Today, not much has changed about mom jeans besides getting a little more form-fitting around the waist.
