Looks like Dolly was sporting a somewhat see through top when she was on Conan back in 01.
Dolly has always known about what great assets are her breasts ever since she became part of the Porter Wagoner show way back in 1967. At the time, she was kinda thick and very curvaceous and her breasts were quite prominent. Later on, back in 1978, she was in a photoshoot in the October 1978 Playboy where she was wearing a Playboy Bunny outfit/costume. By that time, she had lost a lot of weight and got some breasts implants, and she has had plenty of plastic surgery ever since. She is now 78 years old, but she looks a lot younger than that due to face lifts.
