In the Bay Area, fashion is just another opportunity to pitch your app. Startups hand out logo and slogan-covered shirts to all employees, creating bands of boy billboards that roam around San Francisco's tech-chic neighborhoods.

Typically, work shirts are only worn at the gym. But in Silicon Valley, employees take pride in wearing their work out in public. And new Tumblr, Dudes in Startup Shirts, is documenting the fashion of the startup scene.

Let's take a look:

Tech's pigpen of misogyny may be trying to shake its "brogrammer" reputation, with tech reporters insisting that most men in tech aren't bros, but this isn't helping. The only thing worse than naming your startup after a beer synonymous with frat boys and homelessness is slapping "Brogrammer on Duty" shirts on that backs of your post-pubescent personnel.

This beautiful bathroom selfie via Naranya Labs reminds us that life is an ephemeral bummer, so "build stuff that matters." For context, Naranya Labs is a startup accelerator that previously backed a "fashion-oriented" social network.

Yaround, a "local social network," launched in 2012 and has garnered an impressive 18 likes on Facebook since then. Yaround anymore? Apparently not.

Good luck with that.
