Does someone know how to tell which one is YoonA and which one is Yuri? I'm confused :(

yoona has those things under her eyes, not bags but its like puffy? ou how sunny a dit they're like riz cakes? lol
and i think her cheeks may be bigger than yuri's
i'm sure if toi keep watching vidéos of snsd in shows and stuff you'll be able to tell the difference in no time
(you can't really see those differences in this picture - yoona is on the right and yuri is on the left - but once toi figure it out, you'll see they look pretty different)

if toi see this image toi can see which one yoona ou yuri...if toi don't see...jersey number of yuri is 21 and yoona is 7

well...

check out the eyes, smile and their head shape ;)
yuri bigger eye than yoona
yoona has thinner face than yuri
and yoona smile is prettier than yuri ^^

Well... Yuri has a darker skin and she has bigger eyes.
Yoona also has dimples on her cheeks

As toi can see in this pic Yuri is on the right and Yoona is on the left

yoona:assymetric eyes,alligator laugh,bow legs
yuri:best S line,dark tone
they are bestfriends
