Ask HN: Is this worth building?

I have been working off and on on this for a couple months, and I think one last push over the next month should get it done. Is this just a novelty? I will have a bunch of out of pocket costs, namely initial inventory, and testing which designs sell if any, (how's my service? vs Do you think I am cute). Anyone have any suggestions on things, other than that landing page...its not great, I know.

Why can't I just print my own t-shirt with my existing number?<p>Women are protective of their numbers and don't go around texting total strangers.<p>Women won't wear the shirt, and I wouldn't text someone wearing them. Desperate much?<p>How about, "Do you think I'm cute? Come talk to me"

Do a test. Invite a few friends for a "social experiment" to a bar or party and let them wear a couple test shirts. Forward the info to yourself and see if people use it. Do this a few times and you'll have your answer.

why i would like to text someone i don't know?
