LinuxChix miniconf at LCA 2008. Mostly worn while exercising :)
LinuxChix/Haecksen miniconf at LCA 2010. (LCA 2009 had such a miniconf, but there was no t-shirt.) This is a great t-shirt - check out the back, too - and nice to have a v- neckline for a change. Although I waver on the benefits of having things directly printed across my bust. :)
Linux.conf.au 2010. Really nice tee - good fit, women's cut, soft fabric, nice designs. Looks a lot artier than most of my other geek t-shirts. Unfortunately the designs have faded/worn a bit so they're hard to see.
Awesome design - 20th anniverary shirt from the Electronic Frontier Foundation. even though the shirt is a bit tight I love this design so much I'm still prepared to wear it!
Also, yay not black or white!
