Never give gloves as a present...
...well, you can, but you must also receive something in return, or you'll both have bad luck.
Gloves are attached to a whole host of superstitions , dating back to Medieval times and the days of chivalry, when Knights wore a lady's glove in their helmets. It's also bad luck to drop a glove, and then pick it up yourself - derived from the custom of a lady dropping a glove in the hope a prospective lover picks it up.
