Hello! Being that the holidays are coming up, I'd like to purchase my husband a necklace hes wanted. Just wondering if anyone thinks for a approx. 5'9 or 6'2 tall man if a 20" necklace chain will look 'good enough' or does it need to be longer or shorter so the pendant looks about right... Thanks everyone, just need advice to get an idea as to what size of chain I should buy for the pendant.
