LH will reimburse 50% of the cost of any clothes only. 100% is for toiletries.
On the side note; When on some occasion my bag didn’t arrive I went shopping straight from the airport.
While LH delivered it on the next flight, destination airport bag office lied that my bag is on the way, while it was sitting at the parking spot for a few hrs. And then magically start moving after reaching them via phone and express my opinion about their services.
Location device (any) in a bag proof to be really handy in the situation like that.
