Play Garry's Mod without owning CS:S

Really sorry if this question has been asked but I did search and didn’t find anything.

Anyways I’m wondering if there is any way that I can play garry’s mod online on maps that require CSS BUT when I play I won’t see the weapons and see black weapons with purple OR what must be the word ERROR above me. I’m curious if I can possibly download files that make this go away. If doing this is in some way illegal then I apologize for asking but I’m just wondering.
Thanks.

Yes, Downloading Skins from FPS banana and looking for texture replacements for CSS, then yes, that’s the only way

Just buy CSS.

Good sir, if you by any chance would get a dumb download, it would be illegal.
Nobody likes illegal.
