Greetings but I doubt that anyone can give an opinion on this piece off those pictures and even if they did, that opinion is just an opinion and not an authentication.
Since you don’t know if the piece if authentic IMO you should really go to a pro.
First you need to take clear macro setting pictures showing detailing of stitching, hardware, labels etc. Both sides of that fabric care label need to be completely legible to check for typos.
You may not be able to take those pictures without a macro picture app if you’re using a device but you need to do that if you’re selling highly counterfeited luxury goods.
Double check all photos prior to posting and let those that know the tags and fonts see if they see any obvious mistakes before spending money for a pro.
