If you’re in Dublin and have a big event coming up, be it a huge Halloween bash, a fancy-dress stag or hen party, or a themed birthday, you know the thrill and the struggle! You don’t just need a costume; you need the costume! Something that screams creativity, quality, and that, crucially, turns heads.
To me, the hunt is half the fun, but it can be a massively different experience depending on whether you’re a last-minute city-centre shopper, a dedicated online bargain hunter, or a busy parent looking for quality kids’ gear.
To help you skip the “will it arrive on time?” panic and avoid the “is this even going to last the night?” worries, I’ve put together a directory of six fantastic, highly-rated spots that cover all your fancy dress needs across Dublin and beyond.
Ready to find that go-to shop for wigs, masks, and that perfect, unforgettable outfit? Well, I have the breakdown you will need. So, what’s the wait for? Let’s get read in, ya?
TheCostumeShop.ie, The Online Powerhouse
I rely on online delivery so often! My friend Sarah swears by TheCostumeShop.ie, which organizes all the big themed parties. If you need a massive selection and you need it delivered fast, this should be your very first click!
While they are primarily Ireland’s biggest online fancy dress shop, their service is essential for any Dubliner. They operate out of Clonminam Industrial Estate, Knockmay, Portlaoise, Co. Laois. They have top-notch customer service, which comes through in their brilliant 4.8-star rating on Trustpilot from nearly 4,000 reviews.

Their website is incredibly full-on. They have a huge amount of costumes, accessories, and hen party gear. Sarah told me they actually saved her party last year when another supplier fell through. They delivered a huge batch of themed outfits right to her door the very next day! Their focus on speed and volume is truly unmatched.
My Recommendation? Depend on TheCostumeShop.ie when you have a specific, themed outfit in mind or have to make an order for an entire group. Their focus on online delivery makes getting a massive order to your Dublin door completely seamless. That is a total lifesaver when the party date is looming!
My Little Uniform: Authentic Play for Kids
This is such a special and unique online shop, catering exclusively to the little ones! I ordered a few items from My Little Uniform for my niece’s birthday. They were an instant, huge hit! This fantastic company is committed to creating authentic children’s career costumes.
You can find their incredible collection on their website. They have perfect 5.0-star Google and 4.8-star Trustpilot ratings because their products are amazing. The parents operating this store wanted durable outfits that would not fall apart.

These costumes are designed to last through endless roleplay. Think surgeon, vet, or engineer! What really impressed me was that the outfits are machine washable. They are even classified as toys, which means they have gone through rigorous safety testing. It is so much better than the cheap, scratchy stuff you usually find!
If you have a child in your life who loves to engage in imaginative roleplay, this is your destination. My advice would be to splurge on their authentic career costumes: They support open-ended play, and are built to withstand all rough-and-tumble fun.
Fun Place | Halloween & Fancy Dress Shop (Blanchardstown)
If you’re out in North West Dublin and need a strong physical shop, you need to make your way down to Fun Place in the Blanchardstown Shopping Centre! I popped in here recently when I was shopping for accessories for a friend’s stag do. The convenience was totally amazing.
If you are wondering, their store is located at Unit 126, Blanchardstown Shopping Centre, Dublin 15, D15 K064. It has a strong 4.6-star rating from happy customers. They’re great for fancy dress costumes of all ages and specialized items like Halloween makeup.

They have a wide variety that can help you rock that stag party or find the perfect look for the little ones. Being right in the shopping centre makes it a perfect stop when you are already running errands.
My Recommendation? Go to this branch for a wide range. You get to see the quality and size of a costume before buying! You can call them at 087 113 8713 if you need to check on their stock before heading over.
Party HQ Ireland (Liffey Valley): The Local Party Hub
If your needs go beyond just a costume and you’re fully planning a party, the Party HQ Ireland branch in Liffey Valley is the local hub you absolutely need! A colleague at work referred them to me when I was planning a big event.
They were very helpful with all the decor. This large store is located at Unit 9B, The Retail Park, Liffey Valley, Clondalkin, Dublin 22. They are rated 3.3 stars by over 460 customers on Google. They are great for decorations, party supplies, and of course, fancy dress for all occasions.

Although they have a big focus on bespoke balloon decor, they still stock costumes and accessories. Being right beside the M50 makes it super easy to pop in for anyone in West Dublin!
My Recommendation? Use Party HQ when you need coordination for both your costume and your decorations. They make setting the scene easy! If you are organizing anything in the area and need to discuss event supplies, you can reach them at 01 518 0953.
The Silly Shop: North City Essentials
For a quick, centrally-located, and reliable spot in North City, look no more than The Silly Shop! I always pop in here when I’m walking by because they have the best last-minute bits. This fun, well-rated spot is located at 21 Liffey St. Upper, North City, Dublin 1, D01 H303. Currently, it holds a 4.1-star rating from nearly 200 reviews on Google.
As the name would imply, this is an excellent little store for those fun, not-so-serious items. They have all the necessities for making a party fun, from novelty items to simple hats. It is the place to grab that one final little piece of flair that you realize you forgot for your costume!

My Recommendation? Pop into The Silly Shop for those impulse buys, fun gag items, and novelty accessories that add spice to any costume or event. If you need confirmation that they have that one specific joke item, you can reach them at 085 866 7664.
Fancydress Warehouse.ie/The PartyShop (Tallaght): The All-Year Destination
Last but not least, for South West Dublin, Fancydress Warehouse.ie/The PartyShop in Tallaght is an excellent, reliable spot. A friend living out this way insists it’s their absolute go-to since they’re open all year round!
They can be found at the Glen Abbey Complex, Belgard Rd, Tallaght, Dublin, D24 WZXA. This Irish company holds a respectable 4.2-star Google rating. They have a great selection of costumes, wigs, and other various accessories.
They aren’t a pop-up store, so one could rely on them being there if they needed them in the middle of summer or at the rush near Halloween. It’s a key resource for the large suburban community.

My Recommendation? If you are looking for a dependable non-seasonal costume shop outside the city centre – especially if you live in the South West suburbs- then visit The PartyShop. You can phone them on 087 101 9564 if you have any queries before you make the journey.

The takeaway here is this: your approach to fancy dress has to match your deadline and your goal. If you’re a last-minute North City shopper, The Silly Shop is going to be your hero. If you are a planner who needs a physical stop with a huge variety, go to the shopping centers for either Fun Place or Party HQ.
