I haven't been enticed by many designer + mass retailer collaborations, but the Jason Wu for Target line looks pretty, feminine, and fresh. The collection launches on Sunday, February 5th both in-stores and online, with price points ranging from $19.99 - $59.99.

The pieces I like so far are the crepe/mesh neckline dress above and floaty blush pink blouse + paisley (?) skirt, shown below. I'm curious whether this will be a juniors-sized collection like some past collabs (which means pieces may run smaller), or a womens-sized line.
