I just took my 12 year old son in to rent a tux (for his Junior Cotillion). The fitting went fine but when we went back to pick it up, the pants didn't fit--too small--didn't care whose fault it was--we just wnated it fixed. They had a larger size and hemmed them while we waited (took about 15 minutes). It was amazing! I would defintely recommend that you always try things on before leaving the store.
