22 cheap fancy dress costume ideas
Fancy dress parties are great fun, but picking (and affording) a costume can be super stressful. Our list of cheap fancy dress ideas UNDER £20 should put your mind at ease!
If there's one thing you can guarantee about your time at university, it's that you'll be invited to at least one fancy dress party along the way.
You may be blessed with the ability to dream up a standout costume to wear for any theme, but even then you have to navigate the price. Is it really worth spending £50 on fancy dress you'll only wear once?
So start with our list of eye-catching fancy dress costumes, which all sneak under the £20 price tag (including delivery, at time of writing)!
Easy fancy dress costumes for under £20
These are the best cheap and easy fancy dress ideas:
Banana fancy dress
Price: £13.99 (plus delivery from £3.99)
Scientists have spent years trying to figure it out, but we still don't know why banana costumes make everything funnier. But the fact remains that they do, and at this price, you'd be a fool not to get one for yourself.
Horse and cowboy fancy dress
Price: £18.99 (free delivery with Prime)
It's time to giddy up and get your costume sorted – and you needn't look any further than this inflatable horse and cowboy fancy dress outfit.
In case you hadn't worked it out already, the horse is the inflatable part, not the man. But you do get a cowboy hat as part of the set, so that more than makes up for the disappointment of not getting a full-size inflatable person thrown in.
Cheerleader fancy dress
Price: £11.56 – £12.85 depending on size (all free delivery, some with Prime)
This sporty fancy dress costume (suitable for men and women) is available in a range of colours, but we've gone for the red as a throwback to the days of Glee and High School Musical.
What team?! WILDCATS.
Hotdog fancy dress
Price: £16.99 (free delivery with Prime)
You'll be a total snack in this hotdog costume, which one Amazon reviewer boldly claims "does absolutely everything I expected it to".
In fact, the only criticism we'd have is that it only features a line of mustard, and not the correct toppings of mustard and ketchup.
Soldier fancy dress
Price: £5.49 (free delivery with Prime)
Once you've bought this, you just need to get your hands on a cheap green t-shirt (and a pair of green trousers, if you want to go the whole hog) and some face paint, and voilà – you're in the Army!
The only downside – as Julie with the average-size-head points out – is that the sunglasses aren't of a high enough quality to double up as your new pair of shades.
80s fancy dress
Price: £12.99 (free delivery)
Lots of memorable things happened in the 80s – but few more so than the advent of shellsuits, which have been seared into the retinas of anyone unfortunate enough to gaze upon them.
It's worth bearing in mind that neither of these 80s fancy dress costumes includes a wig, so you'll have to source one yourself if you're looking to go the whole hog. But, honestly, we reckon people will probably get the look you're going for based off the shellsuit alone.
Where's Wally? fancy dress
Price: £4.45 – £14.38 depending on size (free delivery with Prime)
God knows how Wally (or Waldo, as Americans seem to think he's called) manages to hide so well in such a conspicuous outfit, but you can't deny that it works. The perfect fancy dress idea if you're trying to avoid someone at the party.
Grim Reaper fancy dress
Price: £11.84 (free delivery with Prime)
Despite what the picture may suggest, this costume doesn't include the scythe. A little annoying, but you can pick one up for just a few quid and hopefully keep this fancy dress costume within the £20 price point.
Just a warning, though – you may feel like death the next morning.
Bottle of beer fancy dress
Price: £17.99 (free delivery with Prime)
Ah, Studmeister – everyone's favourite American-style lager. Who wouldn't want to go to a party dressed as the "lord of lager" (their words, not ours)? Not us, that's for sure.
And as far as easy fancy dress ideas go, you'll struggle to be more on-message at a party than the person dressed as beer.
Mario and Luigi fancy dress
Price: £11.29 (free delivery)
First thing's first: you can either get the Mario costume or the Luigi costume for this bargain price – not both, unfortunately.
They also don't come with the signature gloves, but you can easily find those for next to nothing elsewhere.
Captain Jack Sparrow fancy dress
Price: £12.99 – £16.95 depending on size (free delivery, some sizes with Prime)
Don't let this be the day that you remember as the time you almost bought a Captain Jack Sparrow costume. Buy this bargain fancy dress outfit now!
Pink Lady fancy dress
Price: £15.99 (plus delivery from £3.99)
We get it. You've been scrolling down this list, and now you've seen this fancy dress idea you've thought, "you're the one that I want". You could even say that you and this cheap Pink Lady jacket will go together like rama lamma lamma ka dinga da dinga dong.
Mime fancy dress
Price: £11.45 – £14.98 depending on size (free delivery, some sizes with Prime)
I guess we shouldn't be too surprised that a mimic costume is good at mimicking a mimic.
Either way, this fancy dress costume is the perfect excuse to keep quiet if you're a little shy, or simply don't like anyone at the party.
118 man fancy dress
Price: £12.99 (free delivery with Prime)
118-118. We all know who they are, but nobody knows what they do.
Don't let that stop you buying this costume, though – we know that they're at least good for some affordable fancy dress ideas.
Zoolander fancy dress
Price: £13.33 – £16.19 (free delivery)
There's more to life than being really, really, ridiculously good looking. But let's face it, fancy dress parties are all about appearances, so why not go for this bargain Zoolander costume?
Hippy fancy dress
Price: £16.99 for women, £14.04 – £15.76 for men depending on size (both free delivery, some with Prime)
Dressing like a hippy: the original cheap fancy dress costume. And as Finley notes in his review of the men's outfit, you'll struggle to find a comfier outfit to drunkenly fall asleep in.
Whoopie Cushion fancy dress
Price: £11.49 (free delivery)
As you get older, your sense of humour changes. That's just a fact.
So, while an actual whoopie cushion may be something that only your younger self would have found funny, it's safe to say that this fancy dress costume will still be funny to people of all ages.
Plus, you can be fairly sure that everyone will try to hug you at least once throughout the night. Ah, precious human contact.
Toga fancy dress
Price: £12.90 – £14.49 depending on size (free delivery with Prime)
If your uni doesn't hold at least one toga party during your time there, is it even a real uni? In fact, even if you've not got a toga party coming up, it's almost worth getting this cheap toga costume just because you're so likely to have one in the future.Fancy getting arty and making your own costume?

Caveman/Cavewoman fancy dress
Price: £8.25 for men, £8.97 – £9.07 for women depending on size (both free delivery with Prime)
We'll leave you to guess whether this review was left on the male or female outfit. But we will confirm the value for money here – both of these make for great cheap fancy dress costumes.
OAP fancy dress
Price: £9.95 for women's wig, £5.99 for men's wig (both free delivery)
Once you've got your hands on a wig, all you need to do is hit up your local charity shop and find some cheap-as-chips clothes there. You'll be getting a bargain fancy dress costume and doing a good deed all at once!
Sumo fancy dress
Price: £19.90 (free delivery)
According to the product description of this sumo costume, you'll "toughen up with our adult inflatable sumo wrestler costume!". And just look at the face of the model wearing the costume – there is a man who doesn't take any prisoners.
Morphsuit fancy dress
Price: £17.99 (free delivery)
The beauty of the morphsuit is its flexibility. Literally and metaphorically.
If you're going to the party dressed as anything other than a human, a morphsuit can do the bulk of the legwork for you. Smurf? Blue morphsuit. Toy soldier? Green morphsuit. Butler? Tuxedo morphsuit.
This really is the best cheap and easy fancy dress costume for any party.
