I actually love denim cut offs at the moment - probably because I am going indie though.
They are like jeans and go with everything. T-shirts, blouses, jumpers or really whatever you want!
They are great for the beach, shopping, or a lazy day at home.
Not only that, but they come in loads of colour too. Red and cerise red are my favorite colour for shorts, and they look just as good with t-shirts (and my item of the season, denim jackets).
