Halloween has become one of the UK's biggest seasonal celebrations, with spending on costumes, decorations and themed events continuing to grow.
As a mum, I have already found myself buying three costumes for different Halloween occasions this year. For many families, the costs can add up quickly.
That is why some parents say they are increasingly turning to costume swaps, second-hand outfits and homemade creations rather than buying new every year.
Earlier this month, businesses told the BBC that Halloween had become more important than Christmas for some attractions and retailers, while a survey found 36% of shoppers planned to celebrate Halloween this year, up from 27% in 2025.
From Facebook groups dedicated to swapping outfits to charity shop bargains and creative upcycling projects, families are finding ways to embrace the spooky season without frightening their finances.
For Birmingham mum Mandy Thomas, finding affordable costumes became essential when her daughters were younger.
"I figured out really quickly that I needed to cut costs where I could when Halloween came around," she said.
"There would be a school event, trick-or-treating and a friend's party, and they didn't want to dress up as the same thing every time.
"A friend put me onto these Facebook groups where people swap or sell costumes really cheaply.
"When one of them wants to be a specific character, I search eBay or Vinted and I usually spend a quarter of the original price."
With many costumes worn only a handful of times before being packed away, swapping and reselling outfits has become a popular way for parents to save money while helping to reduce waste.
Charity shops have also noticed increased demand for Halloween outfits.
At the RSPCA charity shop in Coundon, Coventry, manager Ellya Hayden said staff prepare for the spooky season throughout the year by putting aside suitable donations.
"We know that at Halloween and Christmas there's going to be lots of buying going on, and people prefer to cut costs by shopping in charity shops," she said.
"We save any sellable costumes that come in and get them ready for display.
"It's really great to see the kids coming in and getting excited and there's always someone who needs a last-minute costume."
Some costumes sell for as little as £1.50, she said, while items still in their original packaging are often priced at about a quarter of their retail value.
"It's really important to reuse and recycle costumes. We try to repair items where we can so they can have multiple lives," Hayden said.
For some families, saving money means making something from scratch.
In Coventry, Adele Harrison, founder of not-for-profit organisation Cov Cloth, runs workshops that teach children and parents how to transform unwanted textiles and household items into Halloween costumes, decorations and accessories.
She said the sessions help families develop creative habits while showing that many Halloween outfits can be made using items already found at home.
"Our Halloween workshops are especially popular," she said.
"Young people have a great day and leave with homemade Halloween treasures, including accessories, costumes and decorations they've made themselves."
Although families pay to attend the sessions, Harrison said the principles could easily be applied using old tights, cereal boxes and unwanted clothing.
"Our message is: before heading to the shops, use what you already have," she said.
"Get creative, save some money and let your children see how brilliant they are.
"The families may not necessarily see it as a money-saver on the day, but the practices we promote are money-saving creative habits."

Four leading AI models discuss this article
Opening Takes
“Halloween thrift and upcycling could be a modest, durable tailwind for the UK resale ecosystem, but it is unlikely to meaningfully lift overall discretionary demand without improvement in real incomes and consumer confidence.”
The article highlights a rising UK trend of cost-saving Halloween behavior—costume swaps, charity shop buys, and upcycling—that could be a modest tailwind for resale platforms and thrift retailers. Its strongest upside is a potential shift toward circular economy practices that persist beyond a single season, aligning with inflationary pressures and budget-conscious households. However, the piece lacks dollar magnitudes and store-level impact, and some data (36% celebrating vs 27% in 2025) seems inconsistently dated, which weakens a clear earnings read. The real risk is a shortsighted uplift that fades if wages stay flat or consumer confidence deteriorates; the trend may stay niche rather than broad-based spin for retail.
Even if durable, Halloween thrift is still a tiny share of discretionary spend, so any uplift to resale channels is likely marginal and could cannibalize new product demand without providing meaningful core growth for retailers.
“Cost-cutting via resale and DIY is likely to cap new-product sales growth even as participation rises.”
The article frames Halloween as a growing UK spending category, citing a jump from 27% to 36% participation, yet spends most of its length on swaps, charity shops, and DIY. This suggests retailers may capture less incremental revenue than headline participation implies. Without per-household spend figures or breakdown between new goods versus resale/DIY, it is unclear whether total retail sales are rising or merely shifting channels. Attractions and event operators could still benefit, but costume and decoration sellers face margin pressure from extended product lifecycles.
Even with frugality, the nine-point rise in celebrants could lift absolute new-goods purchases if average spend per participant holds steady or events drive incremental consumption the article does not measure.
“The expansion of the Halloween participant base, even via second-hand channels, creates a broader, more resilient ecosystem that ultimately benefits high-frequency, low-cost retail models.”
The narrative of 'frugal families' masks a significant structural shift in retail: the commoditization of seasonal events. While the article highlights second-hand cost-cutting, the 9% increase in participation (27% to 36%) signals that Halloween is evolving from a niche celebration into a primary retail driver, rivaling Christmas. This 'volume-over-margin' shift is a net positive for high-street retailers like B&M European Value Retail (BME) and Primark (ABF), which thrive on low-cost, high-turnover inventory. The rise of second-hand platforms like Vinted is less a threat to these retailers and more a deflationary pressure that keeps the total addressable market expanding by removing the 'high price' barrier to entry for lower-income households.
The shift toward second-hand and DIY could represent a permanent erosion of brand loyalty and pricing power for traditional retailers, turning seasonal goods into a race to the bottom where margins are already razor-thin.
“Rising Halloween participation masks a structural shift from new retail purchases to secondhand/DIY, signaling margin compression rather than genuine demand strength.”
This article conflates two contradictory signals. Headline growth (36% vs 27% participation, Halloween 'bigger than Christmas' for some retailers) suggests robust seasonal demand. But the body documents systematic cost-avoidance: Facebook swaps, charity shops at £1.50, DIY workshops, eBay/Vinted resales. These aren't signs of healthy spending—they're margin compression. Retailers are moving volume but losing per-unit revenue. The RSPCA manager's comment about 'lots of buying going on' masks that buying is migrating from retail to secondhand channels. For consumer discretionary stocks dependent on seasonal spikes, this is a warning: participation up, profitability down.
If total Halloween spend is genuinely growing despite per-unit price deflation, unit volume growth could still drive absolute revenue gains for large retailers—especially if they've optimized supply chains or shifted mix toward higher-margin items (decorations, events, experiences rather than costumes).
The Debate
Responding to Gemini
“Participation growth doesn't guarantee durable revenue or margins for retailers; incremental spend may flow to low-margin or second-hand channels, risking margin compression rather than earnings upside.”
Gemini's take assumes volume-driven upside for retailers like BME and ABF, but participation growth may simply shift purchases into lower-margin categories or second-hand channels, eroding profitability even as headcounts rise. Without per-household spend and category mix data, a 9-point rise could be cash flow neutral or negative if the incremental spend is concentrated in discounters or thrift platforms. The real risk is margin compression, not just top-line volume.
Responding to Gemini
“Participation growth may divert spend to second-hand channels, flattening retailer sales despite higher footfall.”
Gemini's optimism for BME and ABF overlooks how Vinted and charity swaps directly divert spending away from new inventory, not merely lowering barriers. The 9% participation lift could mask a larger channel shift where incremental celebrants buy used, leaving discounters with higher footfall but flat or declining same-store sales in seasonal categories. This dynamic risks permanent pricing power loss if households normalize to sub-£5 costumes year-round.
Responding to Gemini
“The shift toward thrifting creates an inventory mismatch risk for retailers that could lead to significant write-downs.”
Gemini’s 'volume-over-margin' thesis for BME and ABF ignores the inventory risk of seasonal goods. If participation rises but consumers prioritize £1.50 charity finds over £15 retail costumes, retailers face a 'dead stock' trap. They must order inventory months in advance; a shift toward thrifting creates a mismatch between supply and demand. This isn't just margin compression; it’s a potential inventory write-down cycle that could severely damage Q4 earnings for high-street retailers.
Responding to Grok
“Channel shift hurts mid-market retailers more than discounters, because discounters' margins are already priced for deflation.”
Grok and Claude both flag margin compression, but miss a critical distinction: *who* absorbs the deflation. If Vinted and charity shops cannibalize Primark's £5 costume sales, Primark's margins stay intact—they just sell fewer units. The real victim is mid-market retailers (Debenhams-tier) who can't compete on price *or* convenience with thrift platforms. BME/ABF survive because their model assumes razor-thin margins already. The dead stock risk Gemini raises is real, but inventory write-downs hit mid-market hardest, not discounters.
