I vote Ferragamo's Spring Summer 2013 Womens collection the most wearable this season. Any single item from there would fit into every girl's wardrobe and be worn regularly.
The entire collection is in neutral earth tones. What makes it worth your money are the interesting cuts that are expertly tailored and high quality patterned fabrics. It introduces a little edginess and glamour in the usually staid working wardrobe.
In contrast, the menswear collection features lots of bright neon colours in blocks and tie-dye. Very fun and attention grabbing, it occupies a niche unfilled so I guess if this is what you are looking for then now is your chance to buy it.
