Hi! I own a Felicie in Monogram and I think you can find an entire thread of the Felicie on the LV forum
So far its been working great for me! The 2 inserts that it comes with are to die for and I’ve been using them as my “wallets” for other bags (they fit into Chanel Classic Flap in M/L as well as basically any other bag that’s bigger than the Felicie). I’ve been using it constantly and you can change the chain around to your desired length and I haven’t had any problems with it (5’ 3 here). There’s a YT video on how to wear it and it has been super helpful for me!
I think the monogram looks great with casual clothes, but if you’re looking for something more formal then you could probably go with one of the leathers.
That being said, I do have ONE issue with my Felicie that I haven’t found anyone else have yet. I’ll link to my thread so you can see what I mean -

Where I’m from, the YSL isn’t too dressy for casual days, but I do think that it’s extremely common where I’m at and as a result I’m quite biased against YSL small bags/WOCs. Soooo I can’t comment much for YSL haha
