Hi girls,
I would definitly buy either a Chloe paddington (one of my most beloved bags: its is versatile, practical and so elegant at the same time) or a Balenciaga, because it is so practical, modern and you can have it on your shoulder or hold it in your armfold. Louis Vuitton is a classic though, have three bags (Alma, Noe and a black Suhali) and they have been with me for a couple of years now, always elegant and right.
