ORLY/YARLY are ancient memes, not to mention completely ugly.
As for the others, they don't look like a piece of clothing. They're just weird shield shaped stickers.
When I want medieval decals I use the two chainmails, or the peasant shirt, or the leather belt shirt.
The shields don't look like a tabard or anything. They look like they should be on a shield.
A tabard should feature a motif or a sigil/heraldry, not a shield.
