Kourtney Kardashian rang in her 37th year last week, but she's not done celebrating. Today, she took to her Instagram account to share a snap from a previous birthday celebration, and it's safe to say we haven't seen the Kardashian-Jenners look like this in awhile.

In the 'gram, Khloé Kardashian holds Kourtney in her arms flanked by mom Kris Jenner and Kim Kardashian West, while a mariachi band plays music behind them. But it's not their pose that makes this #TBT epic—it's their super tanned complexions, matching hair color, and outfits. With the exception of Kourtney, who wears a flattering jumpsuit, these days we doubt Khloé or Kim would wear a printed maxi dress or a romper and gladiator sandals.

Thanks for the walk down memory lane, Kourt.
