Y: year 2K: 2000 As you can see from the name, y2k is a style inspired by the late '90s and early-to-mid 2000s and it captures the energy (and shopping habits) of our childhood and early teens. This era was undeniably defined by women who ruled pop culture at the time. That means: low waist trousers, crop tops, mini skirts, everything that shine, hand bags, t-shirts with funny lettering and fun colors.
