Save on elegant occasionwear, bridesmaid dresses, and evening gowns with these 2 Coast discount codes.

Money saving tips

  • Sign up for the Coast email newsletter. This provides an instant percentage-off discount code to use on your first purchase, along with early notifications about sales and product launches.
  • Purchase the Coast Unlimited delivery pass if you plan to order more than twice a year. The one-off annual fee of £14.99 pays for itself quickly, especially since you can use it across sister sites like Debenhams and Oasis.
  • Choose the store credit refund option if you plan to shop with Coast again. Opting for store credit rather than a cash refund adds an extra 20% value to your return, helping you save on your next order.
  • Verify your student status through Student Beans to secure a reliable, year-round discount on your purchases.
  • Shop the dedicated "Offers" and "Sale" sections on the website to find discounts of up to 70% or more on bridesmaids dresses, wedding guest gowns, and everyday tailoring.

Delivery and returns

Standard Delivery costs £3.99 and typically takes 3 to 5 working days.

Next Day Delivery costs £6.99 for orders placed before the daily cut-off time.

24/7 InPost Locker and Shop Collect options are available starting from £2.49.

The brand operates a 28-day returns policy from the date you receive your items. All returned apparel must be unworn, unwashed, and sent back in its original condition with all tags attached. Please note that return shipping is not free. A returns fee starting from £2.49 (such as £2.49 for InPost and ASDA, or £2.99 for Evri and Royal Mail) will be automatically deducted from your final refund amount. Online exchanges are not supported, meaning you must return the unwanted item and place a new order.

If you choose to receive your refund as store credit instead of a bank transfer, Coast offers a 20% extra bonus on your refund value. This promotional store credit is valid for 90 days from the date of issue.
