Fall fashion lovers everywhere, rejoice. As the air turns brisk and pumpkin spice is once again dominating our coffees, it's time to swap sundresses and sandals out for cozy attire. While knit sweaters and ankle booties are definite fall wardrobe no-brainers, outerwear can be a little trickier to navigate when trying to accommodate ever-changing autumn temps. Luckily, the higher powers of fashion saw us struggling to find a lightweight jacket for this seasonal transition, and thus, the shacket was born.

Shirt-jacket hybrids are having a moment, and odds are you won't be able to scroll through social media without spotting a shacket somewhere in your feed. One popular iteration of this trend is Free People's Ruby Jacket: an oversized button-down that's solidified its spot as a fan favorite in recent years. If you tried and failed to get your hands on one of the viral shackets this season (they're now sold out in nearly every color and size), we've got you covered.

Thanks to TikTok, we unearthed an affordable alternative to the elusive Free People shacket: the Fisoew Oversized Long Sleeve Button Down on Amazon. It features the same slouchy fit and patchwork details as the Ruby Jacket, but with a price tag of just $40, you can grab multiple colors for the same price as one of the original.

TikTok user @laurenkawano shared the secret Amazon lookalike with her followers, which she dubbed "the most amazing find [she's] ever found," while showing off the dupe's high-quality construction. The jacket comes in a variety of neutral and vibrant hues, and reviewers are obsessed with the ″perfect″ under-the-radar fashion find.

"Love love love this jacket!" one shopper wrote. "PERFECT Free People dupe, for a FRACTION of the price. Great quality and super warm. Just size up at least one, if not two sizes to get the comfy, oversized fit."

If you're like us and can't stand to wait for a Free People restock, head to Amazon to get your hands on one (or multiple) of these $40 shackets to add to your fall wardrobe ASAP.
