Im 5’10 and 195. Titan Super Centurion size 40. The straps I know how to tighten those, but not sure on hips or leg openings. The legs seem to ride up alot more then when new. I can get the suit on in 2min easy.
I always took a marker and pinched and marked the sport where I wanted them taken in. I would also measure how much to be taken out of each hip. I would do that first, then come back and do the legs after you made the first adjustments.
