KS Signature suit 54tall/ pants 48x36

This item comes from a pet and smoke-free home. My son purchased this suit for a friends wedding. he wore it a couple times. In excellent condition. The brand is KS Signature. Suit coat is a 54 tall. The pants are 48x36. they were a tailor pair. that's why the tag says 48/40.. I hemmed them to the length he needed. the color is navy blue. he paid a retail price of $300
