I am thinking of getting myself a First for evening use. I am 1m70 tall (I think that is 5 foot 7?) and as I have lost 10kg recently, it may suit me better than I remember. Trouble is that the store that sells Bbags here doesn't have a First in stock, so I can't try it on. I wear my black RH City and Raisin RH Work alot, so should I just get myself another city?What do you ladies think? A first is too small?
