MILAN — Kick up your heels and live a little. Clothes to lounge in, dresses to dance in — that’s what resort is all about. At Prada and Miu Miu, the mood is flirty and provocative with everything from ultrashort shorts and sexy bra tops embellished with tassels to graceful lace-trimmed dresses in bold colors. Meanwhile, Rebecca Moses is also partial to vibrant hues such as hot pink, turquoise and yellow, often teamed with white. She likes the idea of multipurpose clothing, too, so she’s doing dresses or sweaters and pants that would work equally well at the country club or out for a romantic dinner.
