The Kardashian-Jenner ladies were out in full, fashionable force while celebrating Kylie's 21st birthday, and we're honestly a little shook by how incredible they looked. The birthday girl stunned in a silky cutout dress with long sleeves, Kourtney looked downright divine in a shimmery purple number, and Kendall brought the heat in a strapless black minidress, which she wore with another pair of flame-embellished Prada wedges. Though Kendall's teeny-tiny dress immediately caught our attention, seeing as it put her mile-long legs fully on display, the real highlight of her outfit was her oversize purse.

The 22-year-old model toted a large gi-freakin'-normous orange bag that perfectly matched her heels for her sister's birthday festivities. We don't have a ruler handy, but it looks to us like her zip code-worthy Prada purse was bigger than her entire minidress. We can't help but wonder: what on earth was Kendall "Mary Poppins" Jenner carrying in that thing? Perhaps a celebratory bottle of champagne for her sis's bday? Or maybe a change of shoes in case hers got uncomfortable? For now, we'll have to settle for using our imaginations and simply admiring her purse in all its gigantic glory.
