Accessories are the secret sauce that takes a costume from “nice” to “show-stopping.” A mask, a wig, a prop sword, or the right pair of gloves can sell a character without a single sentence. Think of accessories as the seasoning in a recipe: too little and it’s bland, too much and it’s overpowering. The right balance, though, turns your outfit into an unmistakable persona. Whether you’re prepping for Halloween, a themed party, cosplay, or a stage production, investing in quality accessories pays off in realism, comfort, and the number of compliments you’ll get.
The UK has a healthy mix of specialist fancy dress stores, high-street accessory shops, online marketplaces, and craft stores that all serve the costume crowd. Some retailers focus purely on fancy dress kits and theatrical props, while others offer fashion-forward pieces that you can repurpose for costumes. Below I break down notable options so you can pick the right source depending on budget, timing, and the type of accessory you need.
Party Delights is a go-to for quick-turnaround costume accessories. They stock everything from feather boas and novelty hats to themed tableware and small props. If you want last-minute flair without hunting multiple sites, their range and seasonal collections make it easy to pull together a look. Prices are generally budget-friendly, and they often have multi-buy deals that work well for group themes.
Smiffys is a long-standing UK brand known for theatrical costumes, historically styled pieces, and a huge selection of accessories. If you need era-appropriate hats, historical wigs, or detailed props that hold up under close inspection, Smiffys is worth a look. Their items range from inexpensive to mid-range, and they’re aimed at both casual party-goers and more serious cosplay or stage performers.
The Fancy Dress Shop focuses on a wide assortment of costumes and accessories for every theme imaginable. It’s a reliable source for masks, makeup kits, and novelty items that match specific characters or trends. Their search tools and category filters make it easy to find accessories by theme — pirates, 1920s, sci-fi — so you spend less time scrolling and more time styling.
Funidelia brings continental flair to the UK market, often stocking the latest international trends in cosplay and partywear. If you’re chasing a niche or visually distinct accessory you haven’t seen on every high street, this is a place to explore. They often have licensed items, so look here for branded masks, character wigs, and officially themed props.
Want something unique or handcrafted? Etsy’s UK sellers offer bespoke masks, hand-painted props, and vintage trims that can make a costume truly one-of-a-kind. It’s perfect for folks who prefer artisanal touches like leather wrist cuffs, embroidered sashes, or hand-dyed cloak linings. Turnaround time varies, so order early if you need custom work.
High-street stores are surprisingly useful for costume accessories. Accessorize and Claire’s stock statement jewelry, hair accessories, and makeup-friendly items that translate well into costume details. John Lewis and department stores carry more refined accessories — hats, scarves, and gloves — which are ideal when you want a polished or luxe take on a character. Use these stores when you want quality pieces you can reuse in everyday outfits.
Picking the right accessory is about more than looks. Check materials, weight, and how an item fastens or adjusts. Lightweight foam swords look great at a distance but may flop if they’re underbuilt; metal or resin props look authentic but can be heavy and uncomfortable. For wigs, look at fiber type and length — synthetic wigs in the UK often come in lengths from around 12 inches to 24 inches, and some styles tolerate styling with low-heat tools. For masks and makeup, consider breathability and fit. And, always check if a prop is suitable for the venue — certain places don’t allow rigid or realistic weapons.
Trends shift fast, but a few themes tend to pop up year after year. Retro '80s neon accessories, Victorian-inspired brooches and pocket watches, and fantasy-inspired props like ornate staves or faux-leather harnesses are recurring favourites. Right now, DIY-friendly pieces — think attachable LED lights for a futuristic look or modular armor that clicks together — are gaining traction. If you like standing out, mixing vintage touches with modern materials often creates a memorable, fresh look.
You don’t need to blow your budget for impact. Look for bundle deals, multipacks of small accessories, or multi-role items that can serve several costumes. For example, a plain black cape can be vamped up with different brooches or trim to become medieval, superhero, or Gothic. Marketplaces and discount seasons — particularly post-holiday clearances — are great for scoring higher-end pieces at lower prices. Also, sign up for store newsletters or follow UK retailers on social media for flash sales and discount codes.
Costume rental and second-hand shopping are greener and often kinder to your wallet. Many UK cities have costume hire shops that lend high-quality wigs, hats, and period garments. Renting works especially well if you need something elaborate for a one-off event. For long-term use, vintage stores and online pre-owned marketplaces offer unique accessories with a smaller environmental footprint. When buying new, opt for durable materials and timeless designs so pieces can be re-worn.
If you enjoy making, the UK’s craft stores are treasure troves. Hobbycraft and independent loval craft shops stock foam sheets, hot-glue-friendly trims, feathers, and paints that let you customise masks, build props, or embellish store-bought items. For structured pieces, EVA foam and thermoplastic can be shaped and sealed for convincing armor or helmets. Don’t underestimate simple fixes: a bit of fabric glue, a few inches of ribbon, and a creative patch can transform a basic prop into a statement item.
Matching accessories to a character or period means paying attention to silhouette, texture, and colour palette. For a 1940s look, go for structure: narrow brim hats, tailored gloves, and restrained jewellery. For fantasy characters, play with asymmetry and mixed materials — leather straps, metallic accents, and layered fabrics. Think like a storyteller: what does each accessory say about the character’s life? Worn edges and weathering tell a different story than polished shine. When in doubt, less is more; a few well-chosen pieces will read clearer than a cluttered ensemble.
Good storage keeps accessories ready for the next event. Store wigs on stands away from heat, keep leather items conditioned, and wrap fragile props in tissue or bubble wrap. Small items like brooches, pins, and badges can go into divided compartments so you don’t lose a single piece. For painted or papier-mâché props, avoid damp spaces and sunlight that can fade colours. Taking five minutes after an event to clean and properly pack accessories saves time and money down the line.
A winning costume often mixes bargain high-street finds with one or two standout specialist pieces. For example, pair a store-bought dress from a high-street retailer with a bespoke mask or a hand-crafted belt from an independent seller. This approach balances cost and individuality: general items form the base, and the focal accessory tells the story. Think of it as layering flavours; the base is reliable, and the specialty item is the hint that people remember.
Always check venue rules regarding props and masks. Many public venues ban any items that could be mistaken for weapons or that are sharp. LED elements and battery packs should be secured and insulated to avoid short circuits, and any cosmetic adhesives must be tested on a small patch of skin to prevent allergic reactions. If you’re attending an event with children, avoid small detachable parts that pose choking hazards. Comfort matters too: if a wig feels too heavy after 30 minutes, you won’t enjoy the event no matter how great it looks.
Running out of time? Focus on accessories that change your silhouette or face framing: a wig, a hat, or a mask. Use scarves and belts to instantly alter outfits, and grab multi-use props that can be repurposed. Many online UK retailers offer click-and-collect options for fast pickup, and high-street chains are still the fastest option if you need something immediately. Keep a small emergency kit with safety pins, double-sided tape, and a mini sewing kit — they’re miracle workers when a strap snaps or a hem comes undone.
Choosing the right costume accessories in the UK is part creativity, part strategy. Use specialist retailers for authenticity, marketplaces for unique finds, and high-street stores for convenience and affordability. Mix and match, prioritise key statement pieces, and follow basic care and safety rules. With the right approach, you’ll turn a simple outfit into a memorable character, and likely have fun doing it.
Conclusion: Accessorising is where your costume truly comes to life. Whether you shop specialist UK sellers, browse handmade marketplaces, or craft your own items from materials at a local hobby store, thoughtful accessories elevate the story your costume tells. Plan a little, prioritise comfort and safety, and don’t be afraid to experiment — sometimes the best looks are happy accidents.
