Have to agree with Dana on this one. I don't own any EF, but have become very interested in her line and using what i can from it in creating my own 'vanilla' or essential pieces for my wardrobe. I'm also very interested in how she makes very comfortable clothes look sophisticated and luxe, due to my nerve damage comfort is a must but i don't want to wear sweatpants all the time (they aren't even comfy on me anyways!). I've been spending a fair amount of time in her local boutique and outlet store trying on and photographing myself in many of her pieces - essentials as well as statement.
EF puts subtle and very important shaping in her clothing, the seams are well constructed and suited to the fabric and the role the seam is playing in the particular garment, and her fabrics are very luxurious as well as flattering (ie. they drape so as to not add any bulk without clinging to weird bulges. Not that any of you get weird bulges, but i have one or two ;). You could belt this dress at the waist very easily if you want a change from the empire waist.
FWIW, steph
