Fashion Instagram Is Obsessed With These 7 Affordable Trends

There’s no denying that we editors spend a lot of time on Instagram—scrolling, saving, screenshotting, and taking copious notes on all the coolest items fashion girls have in their homes, their beauty cabinets, and of course, their wardrobes. Yep, we're pretty obsessed with staying on top of the It-items the style set are wearing and loving at any given moment.

While there are certainly plenty of luxury designer pieces to lust over on the 'gram this season—read: Chanel logo tights and the dreamy Prada Cleo bag—today we’re honing in on the buzzing fashion trends that don’t cost a fortune. From backless tops to cozy knit shorts and cool arm warmers, take a peek below as we share some of the biggest trends we’ve been spotting on cool girls all over Instagram that you can score for under-$100.

Arm Warmers



Arm warmers or bolero sweaters have become an Instagram It-piece—with fashion girls styling the open-front shrug over tank tops and turtlenecks alike. It's the perfect extra layer to keep you warm and on-trend this winter.

Matching Knit Sets



You can't scroll Instagram without seeing a fashion girl sporting a cozy-chic knit set. Whether it's a short, pants, or skirt set, it's the most sophisticated take on loungewear right now.



From cozy shearling slipper sandals to easy-to-wear clogs, it's all about comfy house shoes right now (a huge trend we also saw all over the S/S 21 runways). We're 100% here for it.

Knit Hot Pants

While knit bras are still going strong, the more recent trend making waves on Instagram is knit shorts—the really short kind—which could basically pass for undies. Practical? No. Insta-worthy? Heck, yes! Whether worn as part of a matching set or mismatched with a knit cardi, they're the cutest addition to your at-home ensembles. Best to keep the heaters on.

Quilted Coats



Fashion girls love a good quilted moment—whether it's a cool utilitarian jacket liner or duvet style coat—the cushy fabric is all over our feeds.

Bare Backs

Cool cut-outs are certainly having a moment right now, but it's the backless trend, in particular, that's reigning supreme. Whether it's a basic backless dress or open-back knit with delicate tie details, they're an Insta-moment waiting to happen.

Relaxed Leather Pants



Fashion girls have been stepping out of their sweatpants (now and again) to team up their casual tops with relaxed, loose-fitting faux-leather pants—an instantly cool way to elevate your winter basics.
