I just bought the Here's Lucy DVD set. In the episode called "Lucy Meets Donny Osmond" Eve Plumb plays Lucy's niece Patricia. I'm not sure but, didn't Eve also wear this dress on an episode of The Brady Bunch?

It looks familiar, but I don't have all of the episodes taped so I'm not sure.

im not sure but i think she did wear that dress

Actually truthfully I think Marcia wore that dress in the episode brace yourself. The one where Marcia has to get braces.

Julian is correct.

Thanks Julian!
