Hello, I'm looking for some button-down collar shirts and BB is a popular choice from what I read. After browsing their site, they seem to have 3 different fabrics for solid colors in their extra slim line. Can someone describe the practical differences between the 3 and recommend one? I will be wearing a jacket with it maybe 50% of the time and probably will not be wearing an undershirt. Thanks. #1: Described as "end-on-end broadcloth" #2: Described as "pinpoint cotton" #3: Described as "Supima cotton oxford dress shirt"
