USISI SISTER understands that often quick delivery is needed, which is why we provide Express as well as Standard delivery options. All delivery timeframes provided are for your guidance and apply to working days only (excluding Bank Holidays). Whilst we try our best to get your order to you in the specified time, occasionally some things are beyond our control. If there is a delay in receiving your order, please contact us via email at and we will endeavour to resolve with the courier as quickly as possible.

For Next Business Day in the U.K., you must order by midday GMT/BST Mon - Fri (excluding Bank Holidays) to be dispatched that day.

Please note, DHL do NOT ship on Saturdays.

For Express Shipping, please email us at

For Global Express service for the rest of the world, orders placed at any time will be received within 7-10 days (Please note that our goods are shipped duties unpaid, which means the receiver of the good will be liable to pay customs and duties taxes upon arrival except to the EU).

A tracking number will be emailed to the customer once the order has shipped. Customs and duty fees not included, we do not refund shipping costs for customers that reject their packages upon arrival.

Orders are shipped in USISI SISTER branded boxes

If you have any questions about shipping, please contact or refer to our Terms and Conditions.



If you are not completely satisfied please email us at and we will send you instructions for your return. Your return must be within 14 days for refunds or exchanges. 

To be eligible for a return, your item must be unworn, in exactly the same condition that you received it. It must also be returned in the original packaging. Once your return is received and inspected, we will send you an email to notify you that we have received your returned item and will let you know whether your refund has been approved or not. If it is approved, then your refund will be processed, and a credit will automatically be applied to your credit card or original method of payment.

Unfortunately, we don't do free returns at this point in time. Depending on where you live, the time it may take for your replacement or exchange may vary. If you are shipping an item over £50, you should consider using a trackable shipping service or purchasing shipping insurance. We don’t guarantee that we will receive your returned item.
