Make it Romanian specific and I believe people would be proud to wear it. This is why I thought of a domain branding around Romania, it is easy for someone to associate with it.
For example I live in Iasi and having something specific to this area would be great for me. Same if I travel in some other places to have a t-shirt capturing something from there. It is like you would be wearing the memories from different places.
Oh I know. I have t-shirts from lots of areas around the mountains of Romania so I totally feel you. It's a great idea, will keep in mind for sure :)
