Lucky Magazine is one of our favorite sources for great shopping tips. We're thrilled to share this fabulous story from our friends at Lucky!

A lot of burning questions come up in the Lucky digital pitch meeting. Like, should you wipe down your face before washing it off? Does a giant fur coat make pajamas acceptable for wearing in public? (Also: how does one pull that off?) And in their most recent meeting, the staff spent a good 10 minutes debating the right term for shirts with slits [1] up the sides—what earth are they called?!

Unfortunately, while they couldn't come up with an answer, the group did determine that the trend is definitely on the up-and-up. Split-seam tops [2] were all over the street style scene this past fashion month, ranging from ground-skimmingly long (sort of like a more modest crop top, with your front and back covered but your sides exposed), to tunic length (opening right at the waistband, the extra fabric hitting mid-thigh), and with subtle three- to four-inch cuts (over low-slung trousers, just revealing enough to show a tiny triangle of skin).

With so many variations on the piece, there's no one hard and fast way to wear it; lots of options, after all, mean more outfit possibilities.

Lucky's included five great ones spotted on editors, bloggers, and models in the slideshow [3] ahead, along with similar styles you can shop online now.
