I'm planning on splurging on a leather carryall soon, and I was wondering if you guys had any suggestions on which size I should get? - I'm mostly interested in using this as a day-to-day bag. Will the medium or the large be too heavy? - Will the medium fit over the shoulder? I'm more on the chunky side... - On the other hand, would the large be too ridiculously large to use as an everyday bag? I don't carry much. Wallet, a small toiletries/make up bag, a water bottle. - Is it safe to assume that the medium won't really fit a whole sheet of paper/notebook? The measurements are almost exactly paper size.
