We do not recommend big suitcases on the Camino, they are not easy to handle and there’re accommodations with no lift, so you would need to carry it up and down the stairs, Not really practical.
We do not recommend evening clothes or heels, you are not going to need them.
Also valuables in your luggage like a laptop, you do not really need them on the Camino and we cannot be responsible for damage or loss.
