Everyone knows that your 21st birthday is a really big deal. Having it during the pandemic is a really big disappointment... (I mean, who wants to spend their 21st stuck at home with their parents?!) Today's new adults are the true millenials.

There were 4.059 million babies born in the year 2000, and they’re turning 21 this year. This is the PERFECT GIFT for any of them—guys or gals. If you know a Y2K baby, or gave birth to one, show them how very special you think they are with this powerful birthday t-shirt.

What will YOU wear it with?

I designed this shirt for my own Y2K baby who turned 21 this spring. Any of the three colors look great with jeans or white shorts. And the colors are neutral, so it’s not too girly for young men who are having their big day. Pair it with some cool LED sunglasses that you can program to blink “I’m 21” and our Birthday Cake Hat for a fun (for Mom) and embarrassing (for the new adult) birthday photo op.
