Sooyoung became the muse for Isabel Marant.

Earlier in the month, Sooyoung had attended the opening party of the Isabel Marant flagship store, and she wore the brand again for the January issue of 'Harper's Bazaar'. She donned the 2013 S/S season collection, putting aside her usual cute and lovely image for a more mature, sophisticated look.

Sooyoung said, "I like looking casual but not too plain. I don't like tight jeans or kill heels that look uncomfortable. So I like Isabel Marant because it's very feminine without being too tight or uncomfortable. It's easy to mix and match, so I can wear it often as well. I think it expresses how I feel very well, so I even like the designer, not just the clothes."
