1. My favourite bag is my Guess bag. It is a cream colour with G's all over it and a dimante buckle. It's a half moon shape with a leather strap. I like it as i have never seen anyome with the same bag as it was purchased from America. Originality never fails me.
2.It does help if the bag is designer, but it's not a necessity. As long as it's not fake or cheap rubbish, i'll buy a bag from anywhere.
3. Guess and Topshop are my favourite as the are original. They design and sell things that have personaliity and that are different. Most shops such as New Look, DP's and River Island sell the same type of stuff.
4. As stated before, if it's a nice bag, i'll buy it. Yes I would buy online.
I hope this helps. xx
