What are the most basic needs for XC?

I am writing a short article for my local XC club newsletter, aimed at
new XC skiers (or maybe the guys just trying it for the first time
ever), about the basic equipment needed.

Things you need to have a good experience XC skiing:
(assumes little or no grooming, East coast kind of snow (ie; wettish)


The obvious things are;
skis
poles
boots
Clothing
Wipe on wax



Am I forgetting anything essential?

What kind of clothing can I suggest for a newbie? It does not seem
likely that they will buy a lot of XC specific gear..... what kind of
clothing will the average person have around that might be suitable?

Thanks
GR
