Hi, well I def wouldn't consider them good fakes. They are pretty obvious to anyone who knows the brand. The whiskers are symmetrical which is a big red flag. Also, the stitching is sloppy on the back waist patch. The horseshoes are oddly shaped and the arms have no curve. They also are not deep enough and the pocket flaps are not curved enough. the twist in the leg is at the wrong spot and the outseam is not sledged(flat).
Also on yset other jean posting the tag says Joey but the style would be more like billy and there is not a twisted seam.
To your other remarks, I think charity is a good idea for them. It can be safe to buy on eBay. Don't be discouraged because you purchased fakes. When you see a listing you like just private message the link or post it here or just post the pics from the auction. True Religion is widely faked but there are plenty of great deals to be had out there!
If I were you I'd get rid of both fakes. You don't want to be that guy you know? Counterfeit items are illegal so someone might get the wrong idea about you. Also, I don't know anything about Evisu except that I see it alot in TJ Maxx. I'm not really a fan. Someone else on here may know more
