Blake Lively’s a busy woman. Between raising three kids with a fourth on the way and her wildly successful acting career, it’s understandable that she’d forget a few things every once in a while. That’s why we didn’t fault her for making us wait an entire year for photos of her outfit from Gigi Hadid’s NYC birthday party at Zero Bond. Luckily, 365 days after the bash, she finally got around to sharing the look.

On Monday, Lively posted to her Instagram a gorgeous photo of the very Serena van der Woodsen magenta minidress that she wore to Hadid’s 27th birthday celebration last April with the caption, “happy one year anniversary to the day I meant to post this photo.” With the body-con micro-mini by Sergio Hudson (which is currently on sale at Net-a-Porter and still available in a few sizes), she added red, embellished heels from Christian Louboutin and a matching Chanel clutch.

Luckily, we still got a glimpse of the actress’s look on the night of with the help of some photographers outside of the event, but nothing beats a BTS shot from the subject herself, which is likely why Lively’s post is currently blowing up. See it and shop her dress (while you can) below.
