Now like me, most of you who are probably looking into this cardigan is the really cool collar! Now, don't get me wrong, follow the sizing chart they provide you and it'll fit great I guess ahah! I'm 5'7 and just about 140, and the size that was given to me fits great! Besides that, it looks and feels great to put on the cardigan, looking all fancy with the collar haha. It's unique and makes you stand out :), one thing I love about Korean fashion haha! But besides that, as mentioned in the title, there was a small issue with the collar.. The collar would be fine and all, but the only problem would be that one side of the collar is actually a bit longer, so when I try to button the collar down, it shows an extra flap sticking out, it doesn't look too bad haha, I'm a perfectionist but seeing how fast it came from South Korea to NEW YORK (ordered April 22nd at NIGHT time, and arrived April 25th at 11:50AM). I am giving this a 4 stars because of the collar issue. As aforementioned, the collar is the one thing that attracted me the most, if I could I would give it a 4.5 because of the collar, but bump it up to a 4.8 because of the extremely fast shipping! I would not give this a 5 because of the collar issue. Yes I'm picky!, that is just how Koreans are. Overall it is a 4.8/5.0, I highly recommend buying this! Hopefully your collar won't end up like mine, but don't worry, it's not too bad haha!
