I wear size 33 or 34 waist and have 41-inch hips, and the 997 medium (which was "correct" for my measurements - 34C chest) was bloody enormous on me. Snug on the hips, but fit my chest like a sack. I wear an XS in the 997 and while it's not precisely "comfortable" it nonetheless is wearable. I have to belt my pants fairly tightly to hold it down, and I've had some very mild chafing from the seams at my hips, but...meh, not a big deal. Obviously I'm not getting it on by pulling it over my hips though...lol.

I actually like the 988. 2 problems with it though: (1) the binding fabric isn't attached to the cotton tank top fabric all the way around (so it sort of slides up a bit and constricts under my chest, even though it can't properly roll) and (2) because the outer material is cotton it can stick to shirts. I wish it were the nylon microfiber fabric used on the outside of the 998. I also with it were cut like a muscle shirt instead of a tank, just because I have pecs and armpit fat that bulges out horribly.

The binding on both is tolerable. I haven't found any Underworks binder that actually binds well; the lesloveboat ones made of non-stretchy fabric are much better, but sadly tend to look somewhat bra-like so I usually wear an Underworks binder over them to smooth out lines.

Thank you both for the info!
I am losing weight, albeit at a very slow pace (15 lbs since spring  ). I don't wear tight-fitting clothes, so I don't need it to be perfect on the chest - I think being a bit broad-shouldered might help there too. I can handle some discomfort, especially if it means being able to present decently.

Between both your answers, I'm rather torn between the medium and large xD If I get a medium and it's too small, though, it might give me a tangible goal, weight-wise, to work towards...
-pondering-


Some of the other models look neat too- definitely variety there, so I can experiment with a few and see what works for me, I suppose  Thanks, again, for sharing your experiences!
