If you're a ‘ruffles’ kind of gal, then Olive is a must. Casually elegant is the phrase that springs to mind. Olive lets you decide whether to show off your pretty neckline; adding the concealed zip or not is the secret.
Fabric advice
Olive looks a treat in all kinds of fabrics from fluid drape to structured and somewhat heavier fabrics. Whether you go fluid or structured depends on the look you hope to achieve. Poplin, leather(ette) and chambray are some structured options. If you’d like Olive in something drapier, go for silk (satin), lyocell, crepe, double gauze, etc. Olive's finest features shine brightest in a solid fabric or a delicate print like pinstripes.
