They all looked very pretty on her, but my personal favorite is #3
It doesn't really show on the picture, but the gradation looks very beautiful and it suited Yoona really well
-I can't pick one...
-#1 because it makes her looks like a chick!
-She looks beautiful in all of those dresses, but I personally choose #1
-#2, simple is the best. It's the most simple dress out of those three, and yet it looks the most elegant...
-#2 because it brings out her body even more, she suits it really well!
-#1 or #3 because they make her looks like a Disney princess!
-#1. Dress wise, #2 is indeed really pretty. But Yoona looks really really good in yellow.
-She looks beautiful in different way with those different dresses, how am I supposed to choose one?
-#1, yellow is a very hard color to look good in and yet she suits it really well!
-#1, let's be honest... She looks really beautiful in yellow
-#1!!!! She looks like Belle from Beauty and The Beast
-#2 looks pretty... #3 looks pretty as well, but I feel like I've seen that dress before. Did she wear something similar before?
-She looks like Belle with dress #1, so prettyㅜㅜㅜ
