DH is telling me I need a new bag so it must be bad 
My current one is falling apart. I am sooo not in to stuff like this but he's considering buying me something for Christmas and spending, say, £100 on it.
Now, I think it's crazy to spend that much on a bag (and yyy I know a lot of people on here would spend much more) but I am thinking that if I find something I really like, and is decent quality, then it would be worth it. I've carried my current one every day for about 4 years and it cost £15 so I think I'd get the wear out of a more expensive one.
I'm looking for something brown, leather, with a long strap. No decoration, something sensible. Perhaps a satchel or a messenger type thing. Doesn't need to be huge but needs to fit an A5 notebook for work. And I also carry keys, money, phone, tissues.
Seen anything? Or, where would you start looking?
