Clinging on!

It was rather breezy today...

I'm contemplating the fact that I need to invest in a decent photographer or travellers' waistcoat to get round the less-than-generous hand luggage allowance on a particular airline. 

I've done a fair bit of digging around online and there seem to be precious few options - virtually all of which are tailored for men.  (Given that I am a) female and b) on the petite side, I think that any such waistcoat will envelop me like a tent and flap around my knees.)

Does anyone out there have any suggestions? Or items to avoid? I'm currently considering the paramo halcon waistcoat, which looks like the most serviceable and relatively streamlined piece of kit out there.
