f(x) looks good in anything they wear, and this time the girls dressed up in adorable casual wear to model for online shopping site Auction. They shot these photos for the summer and fall line of the shopping website. Since Amber is still not in the best health condition, only four of them could make it to model the clothes. All of their outfits look so good on them because they pull it off nicely. The girls definitely make you wish fall is near.
