I don’t have the Celine belt bag but I have the puzzle in size small. I have looked at the Celine bag but I ended up getting the puzzle because I felt it was more casual and loved the slouchy look esp when you hand carry the bag. While I don’t baby my bags, I do take care for them and I have to say the puzzle is very carefree. I use it when it rains and it does so well. The inside is a nice fabric as well and I love that I can carry it crossbody or by the handle. I think the Celine is a beautiful bag too, timeless and so beautiful in the neutral colors. As the previous posts mention, I do think it looks more dressy because it is more structured but I think it is a very versatile bag. I’m not really helping you am I? One con that people mention is that the small puzzle has a small opening to get your things in and out. I don’t really find it to be an issue honestly. I believe the Celine will have a wider opening based on the design but again I don’t have that bag to say with certainty. Anyways I just wanted to say I love my puzzle. I too got mine on sale way before the pandemic and I agree with the previous poster that you can find the puzzle on sale if you are patient, esp during these times as more retailers are on sale it seems. I have the smooth leather tan one with the silver (palladium?) hardware. Good luck deciding and keep us posted on what you decide!
