On the episode of Clueless where Amber is engaged to a 72 year old billionaire, Bronzi. At the wedding when Bronzi's long lost love bursts through the doors right before Amber says I do, in the shot of Cher and Deon smiling, you can see Cher's white bra above her dark strapless dress right under her arm. If you miss it, the shot is shown again in the ending credits. I guess Cher should be more careful when wearing strapless.
