I bought this jacket in white specifically for summer. it is the perfect weight for the office air conditioning coolness. i wore this jacket with a sleeveless silk blouse and summer skirt. it just looked perfect for a dressier summer outfit. i take a m/l in retailer jackets and went with the large in this because i have a large bust (36d). the medium fit but was just a tad snug through my upper back/front area. the large gave me a little wiggle room so i could wear a little heavier blouse undernea
