Prepare for cool weather and overcast skies for much of the year. The sun shines during the summer months, but temperatures rarely exceed the low 80s.
Pack business attire appropriate to your line of work. Women should opt for knee-length skirts. Colors besides black, navy and gray are widely accepted in the professional environment.
Pack a medium-weight coat, sweaters, ankle boots, gloves, scarf and a hat if you plan to be in Paris during the fall, winter and spring months. A heavyweight pant, such as a cord or chino, is advisable.
Bring lightweight wool, cotton and fleece garments for easy layering during the summer months. Pair summer attire with comfortable walking shoes for sightseeing excursions.
Take nice slacks and a blazer (men) if you intend to catch a show, the ballet or opera. Women, opt for a simple dress or skirted outfit. Formal attire is rarely expected.
Pack an umbrella and raincoat when visiting in the fall, winter or spring.
Remember an appropriate power adapter to recharge batteries for computers and phones and to use small appliances.
