Be warned, if you get black, the shirt may actually be white inside. I ordered the black with white poka dots. The shirt was nice enough an would have looked okay completely buttoned to the top, however, if you wear the neck open like the model shows in the photos, the shirt is not like that. The shirt has an unsightly white liner which totally shows if you wear the neck unbuttoned at all.
