Tux question??

OK ladies I need your help.

We are having a beach wedding so we don't want a super formal tux. FI wants to wear something that has a dark blue shirt. He looks very good in his suits when he wear those dark blue shirts.

Any suggestions? I have searched every wedding magazine and I can not find anything where the groom is wearing anything but a white shirt??

what about a light gray....you could even get a pinstripe one...
