Prepare for sun and mild-to-warm temperatures most of the year. The L.A. sun is dry; rain touches this glamorous corner of the country infrequently.
Pack business attire appropriate to your line of work. Business casual is widely accepted in most offices. Think lightweight materials year-round.
Bring casual clothes with a dressy edge for taking in the sights and spending time visiting friends. Sundresses are great for women, while shorts and a button-down short-sleeved shirt are appropriate for men. Although this town is notoriously relaxed, people tend to dress up versus down.
Take a fleece jacket and a few sweaters to layer when visiting during January, February and March. Pack clothes made of lightweight fabrics such as cotton, linen and rayon for spring, summer and fall visits.
Pack a pair of sandals or canvas sneakers for daytime; bring comfortable but casual dress shoes for evenings.
Remember black will hide dirt and absorb heat; white and ivory will betray dirt but keep you cool. Color in general is very popular in L.A. attire.
Bring sunglasses and sunscreen.
Stash a swimsuit in your bag for a quick dip in a hotel pool or a swim in the Pacific Ocean.
