The item / size I require is sold out - will it be coming back into stock?

I am not sure which size to order – can you help?

General sizing information can be found by clicking the size guide when selecting a size in the product page. However, in some cases sizes differ from this guide depending on the brand. Please contact us if you are not sure, we are happy to measure products or find specific sizing information for you.

I have got a coupon code – how does this work?

From time to time, we provide customers with a coupon code that allows them an offer on their order. If you have one of these codes then simply enter it into the box when you have added an item to your basket. The offer will be applied once you go through to the checkout. If you do not enter the code at this point, we can’t apply it to the same order later on. Please note that codes cannot be used on any sale products or when purchasing gift vouchers.

How do I use the currency converter?

You may view items priced in Dollars, Euros and Pounds. Just select the currency that you want by using the currency drop down menu at the top right hand of the screen. Please note all transactions that go to the checkout will be completed in pounds.


How much is the delivery charge?

The delivery charge depends on what part of the world you are ordering from. Please go to the ‘Delivery Details’ section for more details.

How long does delivery take?

The delivery time depends on where we are delivering the order. You can find details of this in the ‘Delivery Details’ section. We work extremely hard to ensure that we meet the timescale for every order, however please note that delivery times are subject to change during busy periods and during UK bank holidays. If you would like to know more about your order then please contact us.

Do you deliver to work addresses?
