Make pantyhose 21

The Hard version will be released within this year. Excuse me, but I can't answer questions about release dates. Thanks for your understanding.

Add the thigh reinforcement part. Determine the curve using the knee-socks as a reference. I'd like to bring them back someday.

Done.

But when in a suspension, it interferes with some of the butt parts as shown above. So I'll tweak the script to change it to a small shape that is used for butt rubbing.

Well, closed to completion.
