OOwwww, I am late to this one sorry. What a lovely bag and it does look rather splendid on you! I think that your mum will love it, it is a fantastic present, she is very lucky! It is such a classic shape and the leather should wear really well and last for years. It will go with everything and like bays it will do smart or casual with the change of an outfit.
Also, I can totally see that you NEED it on your wishlist, it is very different from the other bags you have, looks fab on you and I think it would be really useful xx
