This shot was taken in mid-December during a Nutcracker rehearsal. I am the second dancer from from the left, and as you can see I am no larger than the other ladies. Admittedly I am a couple of pounds heavier now, but I'm still no one's idea of bulky.
Oh, and in case you were wondering, I've never hit the weight room in a tutu. A leotard and tights, yes, but a tutu never. Tights actually rock when you're deadlifting because they give a little extra protection to your shins. Try it some time :)
