Bats are often a bit complicated because bat furs like myself have all kinds of different answers to the wing + clothing problem
Kinda like headphones on dogs there's a lot of options
Cause you have to decide how much you want the wings showing, if the bat could still fly in that outfit, ect
Part of why my default look is just a shirt or hoodie lol

Honestly I think you did a solid job here
The outfit looks like it help keep the pup warm but still allow them to fly around some and be a general little gremlin (which all us bat folks are, lol)

Good job, very cute overall

Thanks!
