Extra 10% off selected items at Theory with promo code
A general-purpose promo code takes 10% off selected items across the Theory site, sitting between the narrower bags-specific code and the broader sale discounts. It tends to work on full-price merchandise that is excluded from seasonal markdowns, making it useful when the piece you want has not yet been moved into the sale section. Check the eligible product list before checkout, as certain categories may be excluded.
Refer a friend to Theory and you both save
Theory operates a referral scheme where existing customers can share a unique link with friends. When the friend places their first order, both parties receive a promotional discount - typically a percentage off or a fixed credit toward a future purchase. Beyond the standard newsletter sign-up offer, this is one of the few ways to unlock a discount as a returning customer rather than a new one.
Theory outlet section - past-season pieces at reduced prices
The Theory outlet sits separately from the main sale and focuses on past-season stock rather than current collection markdowns. Prices here are set directly by the brand with no code required, and the selection rotates as older lines are cleared. Beyond the obvious savings, outlet pieces still qualify for free delivery and free returns, so the value proposition extends beyond the sticker price alone.
Shop Theory gift cards for flexible present-giving
Theory offers digital gift cards in a range of denominations, redeemable across the full online store including sale items. For recipients who are particular about fit and fabric, a gift card avoids the guesswork of choosing a specific piece and still lets them take advantage of any active promotions when they shop. Cards are delivered by email and carry no expiry date.
Free returns on all Theory orders
Theory provides complimentary return shipping alongside its free delivery policy, meaning you can try pieces at home without risking a return fee if the fit or fabric is not right. This is particularly useful for first-time buyers unfamiliar with Theory's sizing, which tends to run slim across tailored pieces. Returns must be initiated within the stated return window and items should be unworn with tags attached.
Theory newsletter: 15% off your first order plus early sale access
Beyond the immediate 15% first-order discount, joining the Theory email list puts you ahead of sale launches and private shopping events that are not advertised on the main site. Subscribers typically receive a heads-up 24 to 48 hours before public sale pricing goes live, which matters when popular sizes sell through quickly. The welcome code arrives by email shortly after sign-up and is single-use.
Halloween savings at Theory - selected styles reduced for the season
Around Halloween, Theory occasionally runs a short promotional period with price drops on selected autumn-weight pieces - think wool blazers, dark-toned knitwear and layering essentials that fit the season. These markdowns sit outside the main sale calendar and can catch mid-season stock at a lower price than you would see during the rest of autumn. Check the homepage banner during late October for the active selection.
Black Friday deals at Theory - seasonal markdowns on key styles
Theory participates in Black Friday with direct price reductions on core pieces like cashmere knitwear, tailored coats and signature trousers. Rather than relying solely on promo codes, the brand tends to adjust retail prices across a curated selection, making the savings visible upfront. Past Black Friday events have included discounts of up to 50% on full-price stock that rarely goes on sale at other times of year. Watch for the promotional window opening in late November.
Final markdowns: extra discount on Theory clearance lines
Theory runs a last-chance clearance section where end-of-line pieces get a further promotional reduction at checkout. These are typically the lowest stock levels across the site - often single sizes or discontinued colours. Applying the promo code stacks the extra discount on top of the already-reduced clearance price, which can push final savings well past the standard sale percentages.
Extra 12% off men's orders at Theory
A sitewide promo aimed at menswear takes an additional 12% off your basket total. This works on top of already-reduced sale pieces in many cases, so a pair of trousers marked down to £120 drops to roughly £106 when the code is applied. Worth checking the final basket total before completing payment, as certain full-price exclusions may apply.
Up to 60% off Theory Men's Sale with free delivery included
The men's sale at Theory currently reaches 60% off across selected shirts, outerwear and trousers. Beyond the headline markdowns, delivery remains complimentary on these reduced items, which means the price you see is the price you pay with no checkout surprises. Stock is final and tends not to be restocked once a size sells out.
Up to 70% off Theory Women's Sale styles
Theory's women's sale runs deeper than the men's, reaching 70% off on selected lines. You will find past-season dresses, knitwear and tailored trousers marked down from their original retail prices. Sizes go quickly in the smaller brackets, so filtering by your size first tends to surface the best remaining stock. Free delivery applies to these sale orders just as it does to full-price ones.
