This is an outstanding Ben Zuckerman suit in a carnation pink. It is made up of a short sleeved jacket with a half belt in the back, and button detailing on the cuffs of the sleeves. Interestingly, the opening of the jacket is like a polo shirt- it does not button the whole length of the jacket.
The skirt is also worth mentioning- it has two zips, one at each side. I have seen this type of skirt opening, but only in the highest end garments, ie couture Dior and Chanel. This gives a strong indication of how well made Ben Zuckerman clothing was.
This outfit was featured in Vogue in the 1960's, as seen here.
