What the Spice Girls Wore for Their Glam Reunion at Victoria Beckham's 50th Birthday Bash

Victoria Beckham celebrated her 50th birthday in style over the weekend — of course!

The fashion designer and mom of four invited a who's-who of the celebrity world, including her best friends and former girl band: the Spice Girls. The band even got back together to perform their hit song "Stop" for the elite in attendance (and social media, because nothing is private these days!).

Though the ladies were dressed to the nines, their looks were decidedly a different kind of glam than what they might have worn in their heyday 25 years ago. (Except for Beckham herself, who is, was and will always be Posh Spice.)

Let's break down what everyone wore to the fashionable affair.

Beckham, aka Posh Spice, wore a frothy mint green dress fit for the birthday queen. The sheer design gave a subtle peek at her cheeky underwear, and the dress also featured ruching details at her hips and a gorgeous rosette design.

Beckham, who is still nursing a broken foot, accessorized for part of the night with her crutches, but her husband, David Beckham, 48, swept her off her feet (literally) to take her home for the evening. Ever the fashionista, though, she still wore heels, which she showed off once on her husband's back.

Melanie Brown, aka Mel B, aka Scary Spice, opted for a less-than-scary red dress for the evening. She wore a simple but sleek red gown with a plunging neckline and delicate straps. Though she's long been making jokes about her love of animal print, she left her leopard at home for the night!

Melanie Chisholm, aka Mel C, aka Sporty Spice, wore a rather demure one-shoulder black gown that gracefully fell to the floor around her. Though known for her love of athletic-wear, Chisholm amped it up for Beckham's night with this look, which also featured a sexy cutout at the side. On Instagram, she even gave a shoutout to "super fan" David.

Emma Bunton, aka Baby Spice, was anything but baby in her black eveningwear. She wore a button-down gown with a plunging neckline and sky-high slit, which she paired with chunky platforms. For contrast, the dress also featured white cuffs on the sleeves.

Geri Halliwell Horner, aka Ginger Spice, chose a midi-length white Rebecca Vallance Ophelia dress adorned with bows. She accessorized the sweet strapless design with nude platform heels and kept the rest of her glam clean and simple (a far cry from her Ginger days!).

Beckham, who turned 50 on April 17, feted her birthday in London on April 20 with celebrity guests including Tom Cruise, Eva Longoria, Salma Hayek and more.

The birthday girl also had her whole family (minus daughter-in-law Nicola Peltz Beckham) in attendance: husband David, daughter Harper, 12, and her three sons: Brooklyn, 25, Romeo, 21, and Cruz, 19.

The Beckham family let their mom shine on her special day, dressing formally but keeping their birthday bash attire to a muted, black-and-white palette.
