They’re a mix of crew neck and V-neck designs often found in men’s closets. The Henley name comes from the fact that these shirts were the traditional uniforms of rowers from an English town called Henley-on-Thames. Most Henleys will come with buttons that run down the ‘V’ area of the T-shirt. Henleys usually have around 2-5 buttons, and you can wear them as short or long sleeves.
According to Cassandra Campa, founder of Next Level Wardrobe, the Henley complements well to any body type and can accentuate features to make you appear more toned and slimmer. If you’re looking for something casual but sleek at the same time, then the Y-neck is a solid option for you.
