The startup t-shirt is badge of honor in Silicon Valley. A cool company logo, on a well-designed t-shirt signals that you and your team have arrived.

When you see someone walking in shirt from Zynga, Yammer, Hipmunk, Evernote and the like, you know two things: 1. That’s a gnarly shirt 2. If you worked there, you’d have one too. There’s also a good thread of startup t-shirts here on Quora, if you want to see more. (Thanks, Peter)

There’s another practical concern which is alleviated by the startup t-shirt; personal hygiene. An unassailable fact about startup life is the long hours that it takes to push new code, hunt down bugs and get your product ready for the wider world. This often means neglecting personal appearance to make sure that you’re giving it all for your team. The startup shirt proves that you’re not a wild-eyed, disheveled mess, you’re actually a genius who can crank out for code three days with no sleep.

The Next Web: Where did the idea for Design Like Whoa come from?

Gemma Aguiar Design Like Whoa wants to define the startup look for entrepreneursI created my first clothing line FabricatedLA a little over a year ago while I was living in Los Angeles. I used a service in LA to digitally print graphics on tanks and shirts. I loved the technology, so I decided to move to the Bay Area (where I am originally from), purchase a printer, and start a custom printing service.

Who are some designers you admire?

I love casual-wear, and fun, vintage-inspired shirts. A few of my favorite brands are Local Celebrity, Rebel Yell.

Is there anything special to keep in mind when a startup outfits its employees?

There are so many t-shirt styles, colors, and fabric blends out there so your company doesn’t have to choose dull, boxy-fitted tees. Choose shirts you want to wear a lot, because as a startup employee, you will probably visit a lot of events, attend a lot of conferences, and wear your shirt more than anything else in your wardrobe.

Also, don’t be afraid to come up with a unique t-shirt design. Often those are the most memorable, and great icebreakers.

Where did the name Design Like Whoa come from?

After I decided to start a printing service, I needed a company name. I literally started writing down everything off the top of my head. I narrowed down a few names and asked a group of friends which they liked best. Design Like Whoa
was the winner, hands down.

Who are some startups you’d like to outfit?

I would love to make shirts for Instagram, Turntable.fm, and Spotify. I love photo filters, so I use Instagram religiously. I Instagram just about every picture I take. I also love music-related startups. Turntable.fm and Spotify are two of my newer obsessions, so making shirts for them would be awesome as well.
