LOL, I don't wear a bra...
Another trick is to stick a gel or two under the band of your cycling shorts on your thigh, so you don't have to reach back into your pocket with one hand. I have also seen gels strapped to riders arms... This is in long TT's, i.e. 50/100/12 hour... As aerodynamics aren't so importnat for you, I like the idea of sticking them to your bars... But you can also get a pouch that fits on the toptube, for easy access to food stuffs
