Oh, Millennials, you have no idea. Hipsters with your retro clothing - you don't even know! You young whipper snappers missed out on one of the greatest times in clothing... the Underoo era.

But great news: Underoos are back and big enough to fit our grown-up booties!

For those of you who are saying "Under-who," here is a brief (ahem) history lesson: Underoos were produced by Fruit of the Loom. The tighty-whitey style briefs came with a matching undershirt. Some had scenes from your favorite cartoons. Others made you into your favorite character (if your favorite character was a 6-year-old in his skivvies). You could pretend you were He-Man, a Ghostbuster, Chewbacca, Aquaman... girls were even included with Wonder Woman, Barbie, Batgirl and Princess Leia sets.

The day was sad when you outgrew your Underoos, but Hot Topic has your size now. Fruit of the Loom may have given up on most licensed under garments, but the Underoo brand has been sold and has been brought boldly back by (some would say) geniuses, according to Idle Hands.

The underwear and shirt set come in retro packaging and carry a price tag of close to $25, but Hot Topic does have the prices discounted online squeaking in at just under $20.

Who cares if you're 250 lbs. and pushing 40... you can still be Captain America under your jeans.
