Norm, you conformist you,
Staying on the correct side of a yellow line is not a guideline, it is the LAW. It is illegal to drive on the wrong side of the road.
Conforming to Celebrity's guidelines (in their own words, when I spoke to their rep on the phone) for what to wear on their ships IS a guideline, NOT the LAW. It is NOT illegal to wear blue jeans to the after dinner show, or EVEN in the dining room, believe it or not!!
Just thought I'd clear that up for you!
