Swimsuit, Legsuit and Swim Cap

I made the version A and I think it turned out really well. I had no sizing issues except for the crotch lining – it kind of weirdly only covers about half of my crotch (it is only really attached to the front part of the suit). I’m wondering if I did something wrong, but can’t figure out what. It’s not bothersome during use. Just seems… odd. I used a twin needle to finish the elastic. Did the long seams on the serger. I will definitely by trying the boyshort version but need to buy more swimwear elastic. FYI, one adult swimsuit uses almost 5 yards of elastic.
