Can someone help me authenticate my YSL bag?

I purchased it off fashionphile. I’m skeptical after reading many people saying they’ve received fakes even though the site claims they authenticate all bags. I’m not experienced with YSL as this would be my first bag by them, any help making sure this bag is legitimate would be greatly appreciated 🥰

(If this isn’t the correct subreddit for this kind of post- sorry in advance, it’s my first time posting 😅)
