The jumper is comfortable and looks nice both with or without a shirt underneath. I also appreciate that it's ungendered (I'm agender).
I have noticed one or two short bits of string have come loose (about 2 weeks into use), though I don't think it's a quality issue - more likely I just wasn't quite careful enough and caught it in my coat zipper or something. I didn't spot any new loose strings after I started paying more attention, so with a bit of careful handling (or just avoidance of zippers) it should be fine.
Overall, it's probably my favourite piece of clothing at the moment (and I am usually apathetic about clothes, so that's saying something)! I'm thinking of buying a second one to have while my current one is in the wash.
Have a nice day everyone!
