Shirts and shoes are recommended to ride Seattle’s light rail on Jan. 9. Pants? Not so much.

The second-ever “No Pants Light Rail Ride” is planned for that day, and yes — that’s exactly what it sounds like. Check out our coverage of last year’s ride if you’re wondering what that looks like.

My humble opinion: It looks cold.

Participants are meeting at the Westlake Plaza on Sunday, Jan. 9 at 3 p.m. When they hop on the train, the pants come off.

Now, before you go criticizing Seattle for its love of nudity — yes people ride bikes naked here — you should know this idea wasn’t dreamed up in our fair city. Pantless train rides have been happening in major cities for a while, but Sound Transit’s still-new light rail system just recently made them possible in Seattle.

Emerald City Improv is coordinating the pants-free ride, which will run from Westlake Center to SeaTac Airport. There’s more information on the group’s webside.

Seattlepi.com photographer Joshua Trujillo took some video of the 2010 “No Pants” ride. Find that after the jump.
