Hi there, I would be really grateful for a bit of a clue on the sizes of City bag. I am looking at one currently for sale online, which says it measures 13.5 inches long by 9 inches high by 4.5 inches deep at the bottom, 2.5 inches deep at the top. Does this sound right? I have spent hours scrolling through the City photos on here, and some of the City bags look perfect, mid size bags, but others are really big! I realise that often it is hard to get an idea of scale, but am worried because I know people don't always measure or list correctly, and this is a lot to spend on a bag which I cannot return (though I guess if the size is radically different to listing, I could legitimately say it is not as listing....). I would prefer to know if this is likely to be correct sizing? I definitely don't want a whopper of a bag, (I would only fill it and give myself a bad back!). Thank you so much x
