When I rest my luggage on its wheels, the luggage is wider than its height. In the compartment underneath the lid, should I place my suit so that its collar (and therefore the hanger) facing up or one side after I rest the luggage on its wheels?

Thanks. When I put the hanger inside a suit, how should I place the suit into the compartment in the lid? In particular, where should I place the shoulder and collar parts that has the hanger? Horizontally or vertically?

thanks. so should I vacuum the bags right before moving instead of well in advance?
