incredible shrinking

My boobs are shrinking. I put on my one decent bra this weekend, and I don't fill it. Now, the thing is, I'm actually gaining weight, in the form of lean muscle. But apparently, I'm losing fat. And we all know that boobs are fat. By the time PQ roles around, my boobs may disappear completely. That wouldn't be all bad, since I'd rather wear a base layer over a restrictive sports bra. But still. What would be ideal is to have boobs just when I want them. Someone should work on that.
