All Myanmar Youths
Brittany Bowman was travelling with friends when she visited Chiang Mai, Thailand, to visit the local primates.
Nervous Brittany, from Los Angeles, let the baby jump up her leg and clamber up her shorts.
While attempting to swing up to her shoulders, the monkey grabbed on to her off-the-shoulder black top and almost revealed her whole breast underneath.
The shocked tourist was left in fits of giggles as she grabbed hold of her top to protect her modesty.
Brittany said: "It left all of us laughing hysterically, almost to the point of tears.
"I was just so scared that the monkey was jumping on me that I didn't even consider it would pull down my top.
"The owners said he must have been looking for breast milk.
