How It Works

  • A Theory stylist will connect with you to outline your fit, style preferences, and wardrobe needs and curate a selection of styles accordingly.
  • Your personalised edit will be delivered to your home via same-day or second-day service. You have five days to decide what to keep or return.
  • If you’d like to keep everything in the box, there is no action required. Theory will automatically charge your credit card on the sixth day.
  • If you’d like to return an item, it must be dropped off at our Theory Marylebone store, or sent to us and postmarked by the fifth day to avoid incurring charges. Theory will only charge your credit card for the items you keep.

Exceptional style has never been so easy.
