I was able to go in the boutique and try on both sizes, small and medium. I can see why most people would go for the small since it seems more versatile in terms of wearing it crossbody or on the shoulder. BUT I ended up getting the medium because to me, it seemed more substantial and I loved the way it looked on the shoulder. It looks OK crossbody too (a little bigger like messenger bag size), but I really liked how it felt on the shoulder and it was just more huggable! Im attracted to the puffer bc of the softness and puffiness and there was more of that in the medium. I also think there’s many more options for bags similar to the small size (like the small loulou, LV pochette Métis), so the medium to me filled a size gap since it’s smaller than a regular tote bag but bigger than a small-size bag.
