Favourite panties to masturbate to?

I am sure a lot of people do this given there are sub-reddits for this: I love to masturbating in panties and cum on them. So, my question for those who are fan of masturbating in panties: what's favourite panties style and fabric you like to masturbate to? Of course, I am excluding those you can find in a hamper, given there is the extra thrill when that happens! I am asking about the ones in your own possession.

In my case, I don't have a particular favourite but I do love lace so when I cum, I can see it come out sneaking out from the lace. As long as it is not a thong, that is, as sometimes there isn't enough fabric!
