My black one still looks fab, my other shows marks. I would say go and have a look at the ones in store that have been handled and check them for marks. I would have thought the navy would be quite good.
They dont have any in house of fraser thats the only store near me
I bought a Tillie tote last week in sparkle tweed which is really light. I got her in York for the bargain price of £262! I have to say she is one of my favourites.
I think you should get it SB.... You won't be disappointed!
