The lovely Rachael behind Imagine Gnats is a blogger, pattern designer and extremely knowledgable sewist with a great eye for shape and construction and a helpful leaning towards simplicity. Be sure to check out her blog for bookmark worthy information on different types of fabric like chambray, double gauze and knits (beautiful fabric options available here or coming soon). It's like a reference library written by your craftiest friend.
As for her patterns, I love how she can take a silhouette and make it work for lots of body types in a single pattern. The Bess Top is a perfect example of this. Her patterns are designed for a very wide range of sizes (this one is 2 - 20). It's a great shape as either a shirt, tunic, or dress, and easy to sew.
