If your second question is, "How do skaters afford to pay their coaches?", that is a HUGE topic that has had multiple threads all of its own on GS. My attempt at a partial answer below is far from complete:

How the immense costs are covered could depend on the nationality of the skater.
In the U.S. and Canada, parents and families typically pour a lot of money into supporting their skater. Some parents have more than one job; some take second mortgages on their homes; etc., etc.
Many skaters earn some money for themselves -- with jobs that might or might not be related to skating. (A relatively small number of better-known skaters can earn money by performing in professional shows, such as Stars on Ice, Disson, and shows in Europe and Asia.)
Some higher-ranked skaters are eligible for funding from their federation and/or for funding in their country for athletes from all sports.
A small number of top skaters are lucky enough to have corporate sponsorships.
To tie your two questions together, the recycling of costumes in some cases allows skaters to recoup a bit of their original costs. In other words, some costumes are sold to another skater as opposed to being loaned or given outright.
