To be clear, the OP asked us what we thought the image depicted not what the artist was representing. To me that means at least thick-ish leather, not some leather fetish vest and pants. So if it's supposed to be leather armor at least make a stab at making it look like it could be useful, even if padded armor gambeson would likely have been far cheaper and more effective.
Something like this image, at least.
