Dresses and working out

Yes, the two big themes of my life at the moment (pathetic I know) are working-out and dresses for the Christmas parties in December.
I've been surprised with myself about working out, actually. I don't like excercise (many will add their agreement to that). The main thing I dislike about excercising is that people see me all red and sweaty and out of breath. It's not a good look. And sadly I am still young enough to be bothered how I look. So, I bought the treadmill and L got me the Abs thingy and actually, I've been almost enjoying using them! The Abs thingy is fab! It's silly but fun, and it might be working. However, despite all this, my weight has not changed, and neither has my waist size. This is depressing.
Dresses, on the other hand, are terribly hard to find this year. The big problem is that I don't like to re-wear dresses. And it HAS to be a dress. I probably will have to re-wear dresses though, as my attempt at replicating a Girls Aloud dress was a miserable failure.
Darnit.
