The Keeping Up With the Kardashians star wore a leopard print pencil skirt teamed with a green belt and a cage-like black and gold ribbed top, in support of Balmain's head designer Olivier Rousteing on Wednesday (9 July).
However, 33-year-old Kim found herself dwarfed by the catwalk models - including her younger sister Kendall Jenner - as she posed for photographs ahead of the showcase at Palais Galliera.
Captioning a photo on Instagram, Kim said: "The Army #Balmain #IFeelShort."
While 18-year-old Kendall showed off her model credentials during her Haute Couture debut, she also took the opportunity to mock Kim's height!
In a photo showing Kim getting prepped by Olivier, Kendall jokingly said: "She looks up to ME #BalmainArmy."
Earlier, Kim enjoyed the view from the front row - in a very different outfit - at Valentino's Haute Couture Show.
Mum-of-one Kim, who tied the knot to rapper Kanye West on 24 May at the 16th century Belvedere Fort in Florence, showed off major cleavage in a plunging turquoise low-cut gown.
Kim turned heads and highlighted her killer curves in the daring frock and took her seat next to Valentino Garavani, while admiring the fall/winter 2014-2015 couture collection.
Kim being guest of honour was no surprise, as French designer Valentino hosted a pre-wedding brunch for Kim and Kanye's family and friends ahead of their nuptials in May.
