What is millennial fashion?
The Y2K aesthetic refers to the fun, futuristic fashion of the late 90s and 21st century.

Think metallics, glossy lipstick, and a radical departure from the color “black.”

Baby tees are a signature Y2K look, often adorned with playful prints, logos or rhinestones. Pair them with a low-rise dress or mini skirt for a true 2000s look.
