Most clothes "donated" to Haiti wind up being baled, put on ships, and sold in marketplaces throughout Haiti. If you can give them to someone to take with them to an orphanage, I am sure they would be appreciated. For large shipments, they would have to go through customs and that can be a very trying experience. At this point in time, a cash donation is the best way to support organizations in Haiti. That way they can buy clothes locally, buy food locally, etc.
