Kule stripe tees come in 4 different fits and 2 fabric weights. The reason is that each style expresses a completely a different attitude and purpose. For example, The Modern and The Modern Long are great worn alone for warmer days or as layering pieces in the fall and winter months. The Classic, a medium weight cotton, is slightly tailored for a more finished and cleaner look. The Boyfriend, a medium weight cotton, is a more casual and relaxed fit and great for weekends or traveling. I love them all and could never choose just one. One Kule stripe tee is never enough!
