Some independent feds have done a few bra and panties matches, though images/video are scarce.
Monster Pro Wrestling in Canada had a bra and panties match btween Angelica and Samantha. No pictures, no video, and hardly any mention on the internet.

ACW had their pro wrestling prom with an Evening Gown Match in which Allie Kat defeated Christi Jaynes. Again, no pictures or video, but they usually release the entire event down the line.
