The Breton or Basque shirts have been a pretty classic staple for men and women over the years thanks mostly to Saint James. The French brand has cornered the market for the most part due to their quality garments and affordable price points. In Japan the brand offers a couple extra colours that I haven't seen in North America, mostly a few multi-tone Naval shirts, but it's these standard blues and greens that I'll always like most. While Saint James are tried and true in this category, there are a couple others making some great looking variations that I actually like a bit more. Orcival is another brand from France who used to produce the shirts for the French Navy, and have a nice selection of colours in natural hues which are also accompanied by some nice fleece pieces. As well, Canada's own National Anthem have some quality knits currently available overseas that have a more round or crew neck shaped collar on a similar body which I find a bit easier to wear personally. I think the shirt is a must have in the spring and summer. It layers great, can be worn alone and the colours and style work with almost anything.
