Wow that's a good, challenging one... If the date is exact, looking through the Muscle Memory site, this pic seems to have been taken at the 1995 Worlds.I can definitively ID the lady on the right, she's JoJo Sinclair from Singapore, which means we're dealing the with LW class here.
I first though the lady on the left was Frenchwoman Cathy Pilain but she didn't take part to that contest so looking at the list, she could be Italian Marina Vari.
After several deductions I think the lady in red may be Iryna Petrenko who finished 3rd. See the below video of Iryna at the European championships of the same year for comparison:
You're welcome and thanks for confirming Cathy is on the pic, I was certain that was her at first.
