Ollie - First, I totally sympathize with not being able to find flattering tops. Bathing suit shopping is its own special kind of hell. I'm happy to have found one that works - it's a one-piece with a little skirt and is specially designed to tuck the tummy, and I've also started wearing it for pole dancing, since I don't know any moves yet that require a P.O.C. on the torso. But it's also not very modest in terms of cleavage, and while I was able to do an Inverted Crucifix without flashing anyone, when I got upright again there was some spillage. I might have to try a bathing-suit/bra combo. And don't worry about ranting - I feel bad ranting to most of my friends because they don't have the same problem, they see me as lucky, so it's sort of a relief to talk about it with others who really feel the burden and can empathize.
The Floor Body Wave I'm talking about is the one where you're lying on your front, elbows bent and hands by your shoulders, and you start it with the booty up and wave forwards, the boobs are the last thing to wave but they are supposed to come up off the ground. It's in the beginner lessons. I loved the way it looked when Veena did it, so I was frustrated to find myself limited by my anatomy. It's one thing to not be flexible enough for something, flexibility can be worked on, but these puppies can only be helped by surgery.
Your bra size might also have gone up because by poling, you are building up your pectoral (chest) muscles, so bigger muscles might mean bigger band or cup size because the "fatty bits" have more foundation to lay on. Tovah is also right, muscle weighs more than fat. Weight is really just one way of measuring how healthy you are, and it gets an unfair emphasis in the media. I have a scale that I got from Bath & Body Works for $30 that measures body fat and water %, which is nice because then you can tell when you're just carrying a lot of water weight.
One last note, some people can only lose weight by changing their diet, some can only lose weight by adding exercise, some achieve the best success by doing both. I have found personally that I can exercise as much as I want, but I'm not going to see a change on the scale unless I change what I eat, too. There is no one-size-fits-all plan. The best thing you can do for yourself is try new things - variety challenges the body, and the body must adapt, which often results in a change of shape (even if that's not reflected on the scale).
