If you can contact us as soon as possible, we may be able to update the size of the item in your order if it's still in stock.
You can email us at hello@blackmilkclothing.com with your BMC order number or contact us here. We're also available on livechat directly on our website from 7am-3pm, Monday through Friday (AEST).
Please keep in mind that our warehouse ninjas are sometimes even speedier than we expect so we can't guarantee that we'll be able to update your order before it is dispatched, but the quicker you can get in touch with us, the better chance we have!
