Charmian Chen, 22, who is also a model, was feeding long-tailed macaques when one decided to retrieve a piece of corn that had fallen down her top.
As she struggled with the monkey, her dress was forced a little too far down - leaving Miss Chen struggling to maintain her modesty.
Now the photos have made her into an internet star making headline news in her native country and around the world.
The pictures - taken while she visited the Sacred Monkey Forest Ubud, in Bali - have appeared on blog sites and forums in the US, Europe and Britain.
She said: "I was on holiday and at first the pictures were just funny, but when I got back to Taiwan I had all these people trying to add me as friends on Facebook.
"I thought 'that's bit strange', and then one of them said they'd seen the pictures and I was really surprised. The next thing I knew I had TV stations ringing me.
"I was on vacation then in Bali so I didn't mind it, but back in Taiwan I was still studying so I didn't want to become famous just for my boobs."
