Even if you have to don a boring monotone suit for work every day, you can still add some undercover color thanks to Swedish great Björn Borg's line of rainbow underthings ($18 to $44). The tennis-themed concept shop (its first stateside boutique) offers candy-color printed underwear and tanks alongside miniature tennis tables available for customer use. Buy two and get one free when you mention TONY through June 19.
