THE GREAT ONESIE BAR CRAWL
The party starts when the onesies come out.
Some parties have a dress code. Ours have an entirely different idea.
The Great Onesie Bar Crawl brings people together for outrageously comfortable nights out, unforgettable costumes and the shared experience of showing up in public wearing something ridiculous.
Animal onesies. Matching pajamas. Costumes that seemed like a brilliant idea until you left the house. Whatever you're wearing, half the fun is seeing what everybody else came up with.
FROM ONE GREAT PARTY TO A REPEAT TRADITION
The Great Onesie has been bringing pajama-clad crowds together for years.
Our Las Vegas events have filled Fremont Street with colorful costumes, group photos and the kind of unexpected encounters that make for a memorable night out.
We've appeared in local media, welcomed returning crawlers and watched the simplest idea become something people look forward to doing together again.
The outfits get people talking. The party keeps them coming back.
NO HOLIDAY REQUIRED
Christmas pajamas are fantastic. But the Great Onesie spirit isn't limited to Christmas.
We love the idea of bringing people together around a shared theme, whether that means a holiday celebration, a themed bar crawl or another excuse to take your favorite onesie out of the closet.
As we announce new events, you'll find the latest details here at GreatOnesie.org.
THE GREAT ONESIE THROUGH THE YEARS
The Great Onesie story is best told through the people who have shown up.
Take a look back at previous crawls, the creativity of our guests and the moments that made these events memorable.
The costumes change. The friends return. The photos get better—or at least more entertaining.
THE NEXT GREAT ONESIE
Our next adventure is The Great Onesie Christmas Crawl, returning to Fremont Street in downtown Las Vegas on Friday, December 18, 2026.
This 21+ event combines holiday costumes, exclusive crawler drink specials, participating downtown bars and a rooftop after-party at Legacy Club at Circa.
