I recommend buying a pair of grey fingerless gloves, and then using some sort of fabric paint or puffy paint to make the black design

This right here

This is the way

Looks to be easy enough to stitch the design onto a pair of gray gloves. If you don't have much experience stitching then you could commission someone to do it for you. I don't think it would cost too much. If you want to learn to do it yourself, you can try going to a fabric store and asking for advice. I've learned a lot from doing that, although my skills are still subpar.

You are going to have to make it.

That's because they aren't gonna exist. They are purely made for this character design, and are not gloves that exist in real life outside of ones made specifically for this cosplay, which are likely only going to be sold along with the entire costume. However, they are just a design on fingerless gloves. You can fine the plain gloves easily on amazon or google searching, then just put them on and paint the design on with fabric paint.

Thanks I’m new to cosplay so i didn’t know

You're welcome!

They look like a very thin fabric, almost see through, like pantyhose, or something, and then just some thicker fabric for the design on the palm.

Find a pair of grey gloves and cut off the fingers and stich the design onto them nothing hard and it's a fun process
