This next tip is from Eliza: "THANK YOU so much Eliza for your tip"
Hehe just kidding :)
I finally have a find! :D Sorry guys but I don't know where this photo is from (if you know please tell me), I found it randomly. I only know it's at the airport.
Taeyeon is wearing a top from the Korean brand Jessi New York (I never would have guessed that it's a Korean brand after the name; it should be called Jessi Seoul)
Buy it here 154,800 won
