This is such a brilliant question elisabeth and thanks for making me finally face it. It's obvious it's not different body(shape) I (used to) fantasize about, it's actually mostly my own I wasn't accepting.
Frankly, after reading your question, I thought - I haven't got a clue! It suddenly became obvious how silly it is to want something else, but not actually knowing what that else is. The grass is always greener on the other side syndrome. But is it?
Hourglass maybe? I would have been equally lost at the beginning of my style journey, I guarantee that.
Now I know and accept that this is the only body I am ever going to have, I might as well do the best I can with and for it. If it means pen and paper and formulae to figure out how to dress it, then pen and paper it is.
In my fantasies, which i also try to shake off as they distract me from *now* and wrongly focus on *sometimes/whenever*, I'd love just a few pounds less to make it a bit easier to squeeze my perfect thighs in some gorgeous skirts and dresses I had to pass (and - surprise - the world didn't come to an end because I ended up not buying them), but as I said the benefits of getting older and... ahm... wiser are that I am aware of futility of wishing for something I don't and might not have.
