Inquiry regarding pantyhose

Hi everyone! I just watched this video, and really enjoyed it. That said, I’m curious about the type of pantyhose he’s sporting. They appear very ‘lifelike’ (at least to my eyes:P), which has me wanting to purchase a pair myself. The only issue is figuring out what exactly I need. So, fellow crossdressers: please lend a hand; you are my last hope.:D
