what type of human or animal figures are allowed on clothes that we wear? is having just plain figure of human or an animal without any facial features or eyes permissible? what about when there are eyes & other facial features in the logo? pls clear this as I heard many sayings in regards to this.

Yes, when there are no facial features, basically no face, insha'Allah, this is allowed. So just the shadow of an animal or the shadow of a human being. This is the safest thing to do. Some of the scholars mentioned that if it is just eyes, that's it, then insha'Allah, that is also okay. But the safest thing to do is not to have the face at all.
