I have bought twice from Phix clothing and both times i have had a clear, concise selection to choose from. A simple interface allows you to navigate through the site with ease.
The site is also cheap for the style of clothes on offer, and there are usually some brilliant discounts.
After paying, which is a clear and easy method of payment, shipping doesn't take long at all and there is usually a follow up email hoping that you had received your goods.
All in all a very good clothing website
