I made this in Fusion 360 based off of the set photos of the new red and black suit from the upcoming Spiderman Far From Home. I now realize that the legs don't actually appear to be a physical detail, but are rather part of the fabric of the costume.
Edit:
I added another version which is likely more accurate. The center crease in the body of the spider seems to taper off at the end, so I made that adjustment as well as making the head of the spider thinner to match the body better.
