Mom jeans are a style of high-waisted womens jeans that were first fashionable in the late 1980s and early 1990s. They were mainly worn by adult American women in the late 1990s and 2000s and were considered "old" by younger women. However, they have become fashionable again in the 2010s and into the 2020s with younger women from tween and teen aged girls, on up through college aged women and beyond. Mom jeans are characterized by a high waist rising above the navel, making the buttocks appear disproportionately longer, larger, and flatter. They have excess space in the zipper, crotch, and leg areas, and often have pleats, tapered legs, ankle length legs, and elastic waistbands. Mom jeans are often accompanied by a blouse, t-shirt, sweatshirt, sweater, or other shirt that is tucked into the jeans, and often a belt is worn. Mom jeans are different from boyfriend jeans, which have a relaxed fit but tend to sit lower on the waist and have a baggier overall look. Mom jeans are versatile and flattering across multiple aesthetics and body types. They can be dressed up with heels and a blazer or dressed down with a tee and trainers.
