IU and Lee Hyun Woo showed off the wonderful 2015 summer collection for casual clothing brand 'UnionBay' in a round of bright new photos! �Looking like close friends or like they're in a 'some' relationship, the two exude wonderful chemistry as they dress up in couple wear.

The concept entitled 'UnionBay Vacance' shows them vacationing in a carefree and fun manner outside, sitting cutely on a bright blue bench or walking around on pebbles as they soak in the sun. �The outfits are cute and suitably summery as well with their vibrant colors and fun patterns ranging from checkers to classic stripes.
