A bit tight in the chest area for me as I have a bigger chest.  Pigeon chested I am told!!!  I am NOT a fan of the convertible French Cuffs!!!  You can still see the buttons after you put the cufflinks in.  The concept is great I just think there could be a better way to do it - what I don't know but that is not my job.  The color and quality are nice and I love the fact that the buttons match the shirt color as I am tired of all white buttons.  I most likely will NOT purchase another one of these but PLEASE if you like it get one to try it out.  For the price you can't go wrong.  It just doesn't work for me that well!
