I bought this underwear set for my 6-year-old son, who loves Star Wars. I bought size 8, and the briefs are nearly too big. The undershirt, however, is already almost too small. I washed it on cold and when he wore it for the first time it barely touched the top of his jeans. This is my second experience with Star Wars-themed underwear, and both appear to have the same problem. Unfortunately, we won't be trying these again.
