SJS, when I was working outside the home I deducted childcare expenses, including babysitting expenses for my older kids when their school was closed. That would be an example of a clearly work-related expense.
ames, as I understand it only those expenses that are incurred in order to earn income may be deducted. If a kollel wife works outside the home, or runs an at-home business, any expenses associated with that may be deducted.
One interesting point about the origin of a kallah wearing a veil is that Rivkah only wore the veil upon meeting Yitzchok, not before (it does not seem she wore it throughout her journey to c’naan). What does this tell us about the purpose of the veil?
