FAQ – Not A Grown Up

What makes you “Not A Grown Up”?

Because we’re grown-ups in age only. We were raised on Saturday morning cartoons, mall food courts, and no helmets on bikes. This brand is a tribute to the childhood we survived—and the sarcasm we perfected.

How does sizing run?

Our clothes are unisex and true to size. But if you’re between sizes or prefer a roomier fit (hello, snack cake lifestyle), we suggest sizing up. Check the size guide on each product page for the details.

What’s your shipping & return policy?

We ship from the U.S. and most orders arrive within 5–10 business days. Need to return something? No problem. We offer returns or exchanges within 30 days of delivery. Because even if we act like kids, we run this shop like pros.

How do I care for your products?

Wash apparel in cold water and tumble dry low to keep it looking fresh. Stickers are waterproof, dishwasher-safe, and built to outlast your Trapper Keeper. Treat your gear like your favorite cassette: gently but proudly.

I’m new here. What should I start with?

Great question! Here’s what Gen Xers love most:


“Mall Rat” Tee – because we were the food court generation

Donut Pajama Pants – for sleeping in on purpose

Sticker packs – like scratch-n-sniff, but cooler

You can’t go wrong with any of them.


Where are your products made?

Our products are made in partnership with print-on-demand providers around the globe. That means when you order something, it’s made just for you. No warehouse dust, just fresh-from-the-factory retro realness.
