The possible duplicate of Using logo to make myself a t-shirt is still unanswered.
I have read the Trademarks Guideline, but I'm unable to figure out whether I as an individual am wearing T-Shirts
- because I don't wanna be naked
- for advertising reasons
- to merchandise myself
The OP's question was lacking the T-Shirt design, so here it is (notice the realism):
I also read Anna's answer to "Can I use Stack Exchange logos on a t-shirt or other apparel?", but according to the definition of "merchandising" (Wikipedia, not sure if that counts)
... merchandising is any practice which contributes to the sale of products to a retail consumer.
I wonder whether this really applies to single T-shirts worn by myself.
Also note: there used to be a shop to buy T-shirts regularly. Just because this shop cannot deliver as many T-shirts as requested by SO users does not necessarily indicate that we can't create our own.
If T-shirts really aren't allowed, I'll go ahead and buy a Chuck Yeager helmet instead.
