I guess this shouldn't really be called a trend alert, but rather a wardrobe staple as a crisp white shirt should always be an integral part of your wardrobe. But seeing as Katie Holmes was spotted out this week in hers I thought I'd pick the best currently available to share with you. You don't have to spend a lot on a shirt but if you do the tailoring and the fit will obviously be better. However, if you're the kind of person that can't wear white without spilling something down it then I would recommend one of the bargain High Street options. See below for some of the best white shirts currently available.
