Sack dresses are probably the easiest thing to sew. All you need is a pretty fabric (large prints are very welcome) and maybe a belt - I do like my dresses tight at the waist. I bought some remnants of this very lightweight viscose knit (? - there was no label on the boldt, so don't ask me) with this really cool, slightly mysterious, lagoon-like border print and decided that it was the perfect candidate for this super simple sack dress.
