With a tagline like "Change clothes in public without ever getting naked," The Undress has a pretty clear sales proposition, and people are lining up in droves to hand the apparel startup their money.

The "mobile changing room" had a Kickstarter goal of $22,000, but when the campaign ends tomorrow, the final tally will be closer to half a million dollars.

(UPDATE: At the Kickstarter's conclusion, The Undress had received $615,633 from 7,297 backers.)

The problem The Undress is designed to solve—working out and attempting to change into normal clothes without treating your car or gas station restroom as a fitting room. The solution—a dress that you wear that allows you to change without having to do that weird "how many seconds do I have to put my underwear on before someone walks in on me" dance. You'll have to watch the video for the demonstration, but it's an ingenious idea.

At first glance, I wonder how big the market is for people who want to change into clothes without showering after a workout, but $468,000 raised probably answers that question for me.
