Who Are Costin?

Costin is a British luxury fashion label available exclusively online. Costin provides premium quality made-to-order clothing with the added service of enabling customers to customise some of the available garments to their own individual taste. With the exception of scarves, each customer’s chosen garments are made after an order has been placed, thus, everyone who purchases from Costin has the luxury of being individually catered to.

How Does It Work?

Costin offers meticulously designed, luxurious wardrobe ‘staple’ garments, most of which can be modified by each customer to suit individual styles and tastes, with the ultimate aim of producing true ‘investment’ pieces. For example, you may want to alter the neckline and/or sleeve length of our silk jersey tops, or change the hardware colour and/or length of our classic shift dress. As you select the options available to you, the main image on the screen will change so as to display how your dress would look with your selected preferences.
