Trustpilot calculated Theory's score 2.5. The latest review - I absolutely LOVE Theory clothing, but is the worst! I have been wearing Theory for 20 years, but cannot order online at They cannot seem to figure out a glitch that is not allowing me to order on this site anymore-and the items I am trying to order are disappearing. Not very good customer service for a long-time loyal customer..
