  • Where is this service available?
    • Harper Concierge currently serves Greater London (all 32 boroughs) and will appear as a shipping method if you’ve entered a qualifying postcode.

  • How do I place my order with Harper?
    • Add as many items as you wish to buy to your bag. Once you’re happy with your selection, click ‘Try at Home’ at your bag. You’ll be asked to enter your postcode, and if it’s within Greater London, you’ll be taken to our checkout page. Here you’ll select a 1 hour appointment window. No need to pay, you pay for what you want to keep after your appointment.

  • How much does the service cost?
    • The service is free of charge.

  • How do I pay?
    • Once you’ve found your perfect pieces, your Style Concierge will take payment by card at your home (Amex accepted). Harper will return anything you don’t wish to keep to Mary Katrantzou.

  • Is there any obligation to buy?
    • No. Harper helps you find and keep only the pieces you love, while making it easier to return the pieces you don’t — saving you time and effort. There are no hidden or additional charges, nor an obligation to buy.

  • How many items can I try on?
    • We encourage you to try as many pieces as you’d like and take two sizes if you are unsure of fit.

  • Who brings my Mary Katrantzou pieces?
    • One of Harper’s Style Concierge will arrive within your selected hour along with the pieces you’ve chosen to try on.

  • How long do I have to try on?
    • Whether you’re trying solo or opt for complimentary assistance, you’ll have 40 minutes to find your perfect Mary Katrantzou pieces.

  • What is Harper’s complimentary assistance?
    • If you feel you might need a second opinion or fit assistance, select Harper’s complimentary assistance option at checkout and your Style Concierge will be happy to come in and help.

  • What happens if I choose not to receive complimentary assistance?
    • Prefer to try on alone? No problem. Your Style Concierge will simply deliver your pieces and return after 40 minutes — leaving you to try it all on in privacy. Once you’re done, they’ll take payment for the pieces you wish to keep and take-away the pieces you weren’t so keen on.

  • Who do I speak to if I have questions about my appointment?
    • To ask questions about your appointment, simply reply to your order confirmation SMS, call Harper on +44 (0)333 939 8123, WhatsApp on +44 (0)753 922 7126 or email
