Smiffys Discount Code December 2025

More Ways to Save Money at Smiffys

Whether you're planning for Halloween, Christmas parties, or World Book Day, Smiffys has built a reputation for making fancy dress affordable. From their quarterly clearance refreshes to seasonal bundle deals, there are plenty of ways to cut your costume costs without compromising on quality. Their newsletter delivers exclusive discount codes and costume inspiration, while strategic timing around their major sales events can save you serious money. Here's your complete guide to shopping smarter at Smiffys.

How to Apply Your Smiffys Discount Code at Checkout

Getting your Smiffys discount to work is straightforward once you know the steps. Here's exactly how to apply your savings:

1. Add your costumes to basket — browse and select all the items you want
2. Head to checkout — click the basket icon when you're ready to pay
3. Look for the discount code box — it's usually labelled 'Promo Code' or 'Discount Code'
4. Enter your code carefully — type it exactly as shown, watching for capitals
5. Click 'Apply' — your discount should appear immediately in the order summary
6. Complete your order — finish payment once you've confirmed the savings

If your code isn't working, double-check it hasn't expired and that your order meets any minimum spend requirements. Some codes only work on full-price items, so they won't apply to already-discounted clearance costumes.

Up to 80% Off in the Clearance Section

Smiffys' clearance section is where the real bargains live, with discounts reaching up to 80% off costumes and accessories. The section gets refreshed quarterly, but the biggest updates happen in November and January — perfect timing if you're planning ahead for next year's events.

Where to Find Clearance Deals

You'll find the clearance section in the website footer under 'Special Offers'. It's worth bookmarking because stock changes regularly, and the best deals disappear fast. The selection includes everything from character costumes to party accessories, so whether you need something for a themed party or just want to build up your dress-up collection, there's usually something worth grabbing.

When to Check for New Stock

If you're not in a rush, check back every few weeks. New items get added as seasons change, and you might spot that perfect costume at a fraction of the original price.

Seasonal Sales Calendar: When to Shop for Maximum Savings

Timing your Smiffys shopping around their seasonal sales can save you 15-30% or more. Here's when the biggest discounts typically drop:

• Halloween Sales — Start in early October with 15-30% off spooky costumes
• Black Friday & Cyber Monday — Deep discounts across the site, with Cyber Monday often offering the better deals
• Christmas Sales — Bundle deals and promotional offers throughout December
• January Sales — Post-holiday clearance with some of the year's best prices
• World Book Day — March promotions on character costumes for school events
• Summer Sales — Mid-year clearance to make room for new stock

The key is shopping early in each sale period. The most popular sizes and designs sell out quickly, especially during Halloween and Christmas. If you spot something you love at a good price, grab it — these sales move fast.

Free Standard Delivery Over £25

Smiffys keeps delivery costs low with free standard shipping on orders over £25. That threshold is pretty easy to hit — a single adult costume often gets you there, and adding accessories or a second costume definitely will.

Shipping Countdown Feature

They also run a shipping countdown on their website showing exactly when your order needs to be placed to get dispatched on the next working day. It takes the guesswork out of delivery timing, which is brilliant when you're cutting it close for a party or event.

Making the Most of Free Delivery

For orders under £25, standard delivery charges apply, but it's often worth adding a small accessory or two to hit the free shipping threshold. A wig, some face paint, or party props can complete your look while saving you the delivery fee.

Newsletter Subscribers Get Special Offers and Costume Inspiration

Signing up for the Smiffys newsletter is one of the smartest moves you can make. Subscribers get special offers, costume inspiration, and party ideas delivered straight to their inbox — it's like having a party planner who also saves you money.

What You'll Receive

Past newsletter offers have included savings of up to 20%, and subscribers often get early access to sales before they go public. The emails aren't just about discounts either — you'll get costume inspiration, party planning tips, and ideas for themed events throughout the year.

How to Sign Up

The signup is quick and free, and you can find the email subscription form in the website footer. Just enter your email address and you're in. You can unsubscribe anytime if you change your mind, but most people find the combination of savings and inspiration worth keeping.

Student Discount Through UNiDAYS

Students can save money at Smiffys through UNiDAYS verification. The student discount gives you a percentage off your order, which is perfect for university parties, society events, or just having fun with friends.

To get your student discount, you'll need to verify your student status through UNiDAYS. Once verified, you'll get access to the discount code that you can use at checkout. The process is straightforward and only takes a few minutes.

Student discounts can't always be combined with other offers, so check the terms before you checkout. Sometimes you'll save more with a general sale or clearance price than with the student discount, so it's worth comparing your options.

Bundle Deals and Multi-Buy Discounts

Smiffys offers special bundle deals and multi-buy discounts, especially during their December Christmas sales. These deals are perfect if you're shopping for a group, planning multiple events, or just want to stock up on costumes.

Bundle deals typically group related items together — like a costume with matching accessories — at a lower combined price than buying separately. Multi-buy discounts give you savings when you purchase multiple costumes, with bigger discounts as you add more items.

If you're organising a group costume theme or shopping for the whole family, these deals can add up to significant savings. Even if you don't need everything right away, costumes don't go off, so buying ahead for future events makes sense when the price is right.

Help & Support for Your Orders

Bulk Order Discounts

Planning a big group event? Smiffys customer service can sometimes offer exclusive discount codes for bulk orders of 5+ costumes. It's worth giving them a call if you're organising a work party, hen do, or large group costume theme.

Price Matching

Customer service representatives can occasionally match competitor pricing when you show them evidence of a lower price elsewhere. If you've found the same costume cheaper at another retailer, it's worth asking if they can match or beat the price.

Getting in Touch

You can reach customer service through the 'Contact Us' link in the help section of their website. Having your order details ready and being polite goes a long way — they're more likely to help when you're friendly and prepared.

They're also active on social media with links to Facebook, Instagram, TikTok, YouTube, and Pinterest. These channels are great for seeing their costumes in action and getting inspiration for your own looks. Plus, they sometimes share exclusive offers or flash sales through their social accounts.
