Yep, we're pretty obsessed with staying on top of the It-items the style set are wearing and loving at any given moment.

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.

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.
