Get the Titan Super NXG+, regular stance.
I would get you either a size 48 or a 50, probably a size 50.
If it's slightly too big, get a saddlemaker or shoemaker make a single stitch down the sides, you will have to get the bands sewn in slightly anyway for it to fit perfect.
Buy suit slippers while you're at it, will make getting the suit on a much easier task.
Use the suit for a couple of sessions before having it sewn in, since it will slightly widen. Also, since you apparently don't want it too tight... Don't make it too tight.
