With the advanced contemporary market becoming increasingly important at retail, Thakoon Panichgul has amped up his Addition line. The spring 2013 collection is light, breezy and primed for the sales floor — yet not at the expense of interesting details. Many of the pieces were denim-inspired, some worked in a Tencel fabric that mimicked the aesthetic. There were chambray blue wide-leg pants and basketball shorts, and a great dress made up of a denim-esque vest with a short, filmy skirt. Crocheted dresses and shirting with volume in the back rounded out the mix.
