I think there’s enough space for a bottle and book, plus compact wallet, tissues etc. I can put a book (my son’s), iPad mini and a small bottle in my Petit Violette bag. Here’s a pic. Their website also has a video to show what fits in the bag which is accurate and helpful.
Also the bag is surprisingly light weight and comfortable when I carry it on my shoulder. I’m petite like you so I chose the petit bag instead of the regular size. Hope this helps!
Thank you so much for the picture, that's very helpful! I watched the video but I don't like how you can't actually see the inside with the stuff hah. I am very picky when it comes to bag sizes.
I'm so excited to get this bag -- it will be my gift for myself when I finish my PhD in a few months. Can't wait!
