I think jisoo is objectively gorgeous and is literally the epitome of south Korean visual standards but Miyeon looks a bit more tan here and I find that more appealing so I'll go with her.
Never really found irene attractive so it's an easy win for the other two.
Miyeon looks pretty but her pic looks the least bareface. Either she has light make up on or the video is beautified slightly cos her skin look too shiny and flawless?
