G-Star is running a Singles' Day sale with up to 40% off plus an extra 11% off sale items, which is the main offer right now and works best when you are shopping selected sale styles. For autumn pieces, a separate 25% off deal through the newsletter page gives strong savings on seasonal clothing, and if you are a first time CLUB-G member, a 15% welcome discount on your next order is worth considering alongside these other options.
Buying selected sale styles The Singles' Day sale takes up to 40% off chosen items, then adds a further 11% off those sale prices in your basket. These discounts apply automatically when you buy qualifying sale pieces. On a €100 sale item, for example, 40% off brings it to €60, then the extra 11% off leaves you with €53.40, saving €46.60 total. Use this offer whenever you are buying from the selected sale range.
Shopping autumn styles outside the Singles' Day sale If you want autumn clothing that is not in the Singles' Day promotion, the 25% off selected autumn styles through the Irish newsletter promotions page gives a straight reduction at checkout. On a €80 autumn piece, this saves €20 and brings the total to €60. You will need to visit the newsletter promotions page to access this discount.
Your first CLUB-G order Joining CLUB-G gives you a 15% welcome discount on your next purchase, though this excludes sale items. If your first order is full price clothing, this can be valuable. On a €100 full price item, 15% off brings the total to €85, saving €15. After that first purchase, CLUB-G membership also lets you earn points at €1 per €20 spent, redeemable against future orders, and gives you access to sales before they open to everyone.
Building a larger basket across multiple items Once your order totals over €50, you qualify for free standard delivery to the Republic of Ireland, which saves the delivery cost on top of any discount. If you are planning to spend €50 or more and paying at checkout, ensure your subtotal exceeds that threshold to get free delivery. Newsletter subscribers get free delivery on every order regardless of spend, so if you sign up you save on shipping even on smaller purchases.
Returning an order with at least one full price item Any order containing a full price item qualifies for free returns within 30 days using the included DHL label at an An Post shop. If you are buying a mix of sale and full price pieces, you get free returns; sale only orders do not have this option. This removes the risk if you want to return something later.
Comparing the main discounts for the same basket: work out what you are buying first. If your items are in the Singles' Day sale, the up to 40% plus 11% extra takes priority. If you are buying autumn styles that are not in Singles' Day, check whether the 25% off autumn deal applies and calculate the final price. For a first CLUB-G purchase of full price autumn clothing, compare the 15% welcome discount against the 25% autumn offer and take whichever leaves the lower total (though the 25% autumn discount may not apply to all autumn pieces or may require newsletter signup). Remember that newsletter subscribers get free delivery on all orders, which is worth adding to your comparison if the free €50 threshold would not otherwise apply. Free returns are available once your order includes at least one full price item, so factor that into your choice if you are unsure about fit.
Our records show that over the 12 months to November 2026, G-Star listed 11 offers on our page, with the biggest percentage sale reaching up to 50% off in September 2026. Our team recorded no checks of G-Star discount codes at checkout in that period.
To use a G-Star discount code, add your chosen items to the basket and enter it in the voucher field before paying. Check that the reduction appears in your order total. Some promotions apply automatically in the basket, so compare the final total rather than just the price on the product page.
Check each offer's product restrictions and expiry before ordering. Don't assume a welcome offer, member voucher and automatic basket reduction can all be used together.
G-Star offers delivery to the Republic of Ireland, with an estimated delivery time of 3 to 5 days. Orders qualify for free delivery above a minimum spend, while newsletter subscribers receive free delivery on all orders. Payment options include Visa, Mastercard, American Express, PayPal, Klarna and Apple Pay.
You have 30 days to return items. Use the included DHL returns label and take the parcel to an An Post shop within the country of purchase. Returns are free when your order contains a full-price item; otherwise a returns fee applies. Factor that fee into the saving if you're ordering only reduced items and may need to send something back.
Underwear cannot be returned, and exchanges are unavailable. If you need another size, return the eligible item and place a separate order.
CLUB-G combines personalised member benefits with points earned through spending. Points can be redeemed for money off a future purchase, so consider them separately from an immediate basket discount: they benefit a later order rather than reducing the purchase that earns them.
Other member benefits include birthday gifts, giveaways, event invitations and early sale access. These are personalised benefits, not a promise that every member receives the same voucher. Early access may be useful if you have a particular style in mind, but compare the actual price with other available savings before ordering.
Enter it in the voucher field during your order and apply it before paying. Make sure the discount appears in the final total.
Check its expiry, eligible products and any account conditions. The newsletter welcome discount excludes sale items.
Free delivery is available above a minimum spend. Newsletter subscribers receive free delivery on all orders.
Returns are free if your order contains a full-price item; otherwise a fee applies. Eligible items must be returned within 30 days, and underwear cannot be returned.
Compare seasonal sale prices, multipacks and automatic basket promotions. Newsletter offers and CLUB-G benefits provide additional ways to save.
If you're comparing jeans or everyday clothing, browse our fashion offers before placing your order. Compare the total after delivery and any potential returns fee, rather than choosing by the headline discount alone. You can also browse denim and other clothing at J.Crew. For streetwear and casual clothing from different brands, take a look at Urbanstar.
