Running belt/pack for curvy girl?

I am looking for a waist pack to carry a drink bottle, as a minimum, preferably my keys etc. too. I have a very large bum and a very small waist and the couple I've tried either ride up and bounce around within 10 yards or esle I have to drag it in so tight around my waist that I'm virtually cut in half, and the bottle keeps snagging my arm.

I know a back pack thingy would probably be better but I feel a bit overdressed, and I guess these also move aound when carrying very little in them.

Any suggestions? Does anyone have a "woman specific" belt and is it any better?

Virago could you not manage without taking a drinks bottle with you?

You dont say how long your runs are but as long as you're well hydrated before you set off then you should be ok for at least an hour, unless of course you're running somewhere very hot.

 If you just need to put your keys somewhere then maybe a shoe wallet or if an item of your clothing has a small pocket?

J - have checked the nathan one out - it looks quite small and neat, but I can only find it online - I might add it to my Xmas list!

Paul - I don't usually bother, as you say, I don't find the need up to about an hour and a half, but I'm beginning a marathon training programme, and I was thinking about being out for several hours. I do sometimes carry cash to buy something when I'm out, but I hate the change jiggling around in my pocket too! Also I was thinking ahead to the race itself, and carrying my own energy drinks etc. as I can't stand those gel things and they don't like me much either!

You could leave water bottles out for yourself. - ok if you use the same routes for both your short and long runs.

I have a Nathan belt - don't notice it that much. Nathan also do a hand held bottle that straps on rather than needing to be carried. I tried one but as I had a dislocated elbow I was in too much pain to carry it so I can't tell you if they are any good. (I didn't know my elbow was dislocated before hand. I just had to drop the bottle - it was like someone trying to cut my arm off at the elbow with a fire axe).

Oh - some of the Nathan bottles you can just drink from without having to try and open - the handheld I had is like that.
