Can a shirt be converted to hoodie?

Hi, i need to ask this.
Can a shirt be converted to hoodie?
Not by my own but if i go it to a custom shop for example, can they make it hoodie?

 

The print? Yes, you can have a replica made, though you can't go through any online places because of trademark issues, it'll have to legally be "handmade," which will be very difficult to find. Making the shirt itself into a hoodie isn't really practical. You COULD add long sleeves and a hood, and easily stitch on the fabric, but you'd just have a thin and very awkward looking hooded....thing.

 

Easily attatchable if you have your own hood, and take it to a custom fitter.

 

You'd have to replicate the design onto a hoodie yourself, which shouldn't be too hard. Just make sure you aren't violating any copyrights or trademarks.

 

You could sew on a hood but it'd look a little funky. You'd be better off printing onto a hoody.
