Domestic Shipping

For all Australian orders you will receive your item via Australia Post. Australian express post orders will be received within 1-3 business days from the shipping date, depending on whether we have the selected item in stock and excludes Pre–Order items. Standard shipping orders will be received between 2–6 business days if you are located in the Metro area. If you are located in the country please contact your local post office for more information.

The Express Post Service covers 80% of Australian business addresses, private addresses and Post Office Boxes. Service operates between all capital cities (except Darwin and in Perth CBD only) and some major centres. Outside metropolitan areas guaranteed service is to and from townships only. If your item is for an address outside the Express Post network, Australia Post will use the fastest possible transport links, but it won't be covered by the next day guarantee.

If you would like to track your item please contact us at after placing your order and we will track your item. The standard domestic shipping cost is $9.00 and express post is $12.00. All product prices are in Australian Dollar currency and include GST.

Please be aware that your local customs office may apply additional charges, an import tax & duties fee to your goods upon arrival into your country. These charges are the responsibility of the purchaser. These charges must be paid in full by the recipient prior to release of the parcel. For more information on these charges we advise that you contact your local customs department as charges vary from country to country.

Should you refuse delivery or payment of duties and taxes, your parcel will be returned to Mademoiselle X and a credit note will be issued only. The customer is then responsible for the original shipment charges incurred to Mademoiselle X, any import fees on the package, cost of goods if damaged or destroyed, and the cost of returning the package to us. This amount will be deducted from your total merchandise credit note.


Mademoiselle X is delighted to announce that the Afterpay service is now available for all domestic Australian orders!
