When will my first box arrive?

Box 1 shipped in October. Box 2 ships in November, with a new box every month after!

Do I need to subscribe to the monthly program?

You can buy the boxes as one-off items as opposed to subscribing, but you will forgo any discounts that come with subscribing!

Do you ship internationally?

Yes, we do! Please note that all international shipments are shipped duties and taxes unpaid

How do you recommend washing these shirts?

We recommend washing these inside out on a delicate cycle to best preserve the prints on the shirts.

Can I change my monthly subscription shirt size later?

Yes! You can reach out here, and we can make that change for you up to 5 days prior to the recharge date of your subscription: https://maestromedia.com/pages/contactus

Can I change my monthly subscription payment method later?

No. We cannot change this on our end. The best solution is to cancel your existing subscription and resubscribe to the monthly plan with the new card.From there you can either Add shipping address or click on the current shipping address and Edit shipping address.

Can I pause my monthly subscription without canceling it?

Sort of. You can reach out here, and we can skip the current box on your behalf up to 5 days before the recharge date of your subscription, but we cannot truly pause the subscription.
