Japanese star Saya Kataoka held a press conference on Sunday to promote her newly-launched photobook.
According to takungpao, the 22-year-old babe also launched her newest DVD.
On that day, she wore a colourful bikini and was seen holding onto her chest multiple times to prevent a wardrobe malfunction.
However, fans still noticed a malfunction in her photos.
Because her shorts were way too short, it revealed her underwear beneath.
