The Fenix Romper has a front and back V neck and an asymmetrical hemline.  The tutorial comes equipped to guide you through two shoulder strap options.  

The Fenix Romper works well in either woven or knit fabrics.  You'll want to work with very lightweight wovens and knits such as such as satin, challis, voile, crepe, poplin, linen, gingham, polyesters, textured knits, spandex, rayon blends.
