I beg to differ; again, I think having the extra weight helps when it comes to gaining curves (I've got a fairly hourglass figure, but it's a big hourglass!). I got curious, and my current measurements are 38DDD-28-42. That's about a 0.64 waist-to-hip ratio; I can live with that, even if I'm apparently a little bottom-heavy. And yes, it's from HRT alone, or at least from that and eating enough dessert. 😉
But I've been on HRT over 7 years now.
