I know what you mean, I've only had mine since April and still having got to grips with hiding the bag confidently with alot of things I wear. I hate it when the top of the bag flops forward without you noticing and it makes your top stick out. I also hate the fact that when it begins filling up it leaves an obvious bulge alot of the time and the only way to solve that is by emptying, when it really doesn't need emptying yet!
tryingtokeepmyheadup - you mentioned about jeans...I know what you mean, I have bought high waisted jeans which work a treat. If I'm not wearing high waisted trousers then I will try to make sure that what I'm wearing are a soft material...like cargo trousers.
