Look at any celebrity outfit from the past month and we bet they've worn some Ugg iteration, whether it's wedged boots à la Selena Gomez or platform slides à la Gigi Hadid. And while it's hard to compete with the popularity of Uggs, there is one fashion staple that's been blowing up on TikTok, so much so that we might also name this season after it. TheImageDirect.com Welcome to shacket season! If you're confused, keep on reading, and if you know, then you really know. Break apart the word ″shacket″ and you get two words: shirt and jacket, which is exactly what this outerwear essential is. It's a button-down shirt, typically rendered in a plaid print, that doubles as a jacket, as it's usually made from a heavier material, like wool. And Jennifer Lopez just catapulted the piece to a whole new level of popularity. Sure, the #shacket has already garnered more than 37 million views on TikTok, but after this J.Lo sighting, the outerwear staple might really break the internet.

She wore baggy white trousers, white sneakers, a rare Coach handbag that we were not able to find anywhere, topping it all off — literally — with a blue and beige shacket that will inspire even the most shacket averse to get in on the trend. There's a reason celebs like J.Lo, Katie Holmes, and Rihanna have worn the shacket: it's stylish, it's cozy, and it's incredibly easy to wear. Plus, there's always something about a multi-use piece that draws people in. It's extra functional and can be worn for many seasons, making it very much worth the money. Though we're not sure the exact brand behind Lopez's shirt-jacket, we were able to find a plethora of shackets that would certainly earn her — and TikTok's — stamp of approval.
