I have worn these shirts for years now. However, I recently started concealing AIWB, and these shirts show everything. Mainly because they are slim, thin, and longer. They are a very nice fit, but if you are a bit plump in any way, or short, they will be too long or too thin for you. I do recommend these shirts, but just know what to expect. They are without a doubt the best under shirts I have ever worn.
