That whole memorial day/labor day things is a bunch of bunk. It's like the rule to not wear a striped tie with a striped shirt - it's a simple rule for the mindless to follow so they can feel comfortable in being "correct". First off, what is the rule in England, Canada, Australia, France - where they don't have a memorial or labor day (at least, not when we have ours)? So, this is a U.S. specific rule - well, what yahoo made it up? Also, memorial day used to be all over the calendar, particularly in the South where each state had a different day that ranged from April to June - so that's a pretty fuzzy rule. It wasn't codified as a national holiday until 1971 and labor day was in 1894. It's a stupid rule that never applied in the past and was set down for middle class people to know when they could ape the upper classes. I argue, that to the extent there is a rule (and it does/should depend on climate), whites, linens, etc. can be worn after Easter and until the end of August.
