Yves Saint Lauren Blazer with Korean Tags?

uFollowMe Vintage Yves Saint Laurent Ysl 3 Button Up Wool Blazer Old School Style BTS (code:KQ)

Can anyone verify if this is legit or fake? I got this YSL vintage jacket from a thrift store and I don't know about branding. The language is in Korean too. Thanks
