Thank you!
See, in my opinion, medium and small CF are the same in terms of style, look, occasion etc., I understand capacity is different but for me that’s not a major factor (I carry minimal anyway). So when both are put down on a table they give you the same vibe/look so when deciding between the two, it all boils down to the body frame. The medium suits me very well. It could look like a small on me if that makes sense while the actual small would look tiny/toy like and make me look bigger in comparison. This is my very personal opinion regarding these 2 specific bags. I hope this helps!
