When choosing a jacket, men tend to go with the standard “male” colors. Meaning, traditionally, dark colors. But men can look absolutely great in white, off-white, or ivory blazers and suits. If you pair a white jacket with jeans, the look will be summery and casual. If you go for a white suit, it will be suitable for some formal occasions, especially outdoor events like weddings or garden parties.
Three nice examples, my favorite being the one on the left – I like the cut of it:

Keep in mind that a white garment is harder to keep clean than one of a darker color. The end of the sleeves and the collar are bound to get dirty.
