Frequently asked questions about costumes

Size & Fit Guide

Do your suits fit like classic clothing (S, M, L)?

Generally, costumes run "true to size," or even a bit "small" compared to regular ready-to-wear clothing. The cuts are more basic.

💡 Seller's Tip: Don't take chances. If you're debating between two sizes, always go for the larger size. It's much easier to "cheat" (belt, pin) with a costume that's too big, whereas a costume that's too small is unwearable.

What is the number one mistake when choosing a size without trying it on?

This is to forget the context of the event.

💡 Seller's tip: Think about what you'll wear underneath. For the Nice Carnival or the Lemon Festival in February, it's cold! If you take your exact size, you won't be able to slip a sweater or coat underneath. Take a larger size to avoid a "sausage-like" effect.

Is it possible to alter a standard suit?

Yes, most costume fabrics are lightweight and easy to work with, even if you're not a seamstress.

💡 Seller's tip: Prioritize comfort above all else so you can dance and move freely. A slightly loose costume can be tailored for style, but fabric that is too tight risks ripping at the seams in the middle of the party.

Makeup & SFX (Special Effects)

What makeup brands do you sell?

We do not focus on a single brand, but rather select products known for their reliability.

💡 Seller's advice: Don't just look for a logo or a price, look for safety. We don't have a "star" brand to mention, but we guarantee that all our stock complies with standards, is 100% tested and approved, and will not endanger your skin or eyes.

Do you sell technical supplies (latex, fake blood) or just face paint for children?

We sell genuine technical equipment: liquid latex, scar wax, fake blood, and colored contact lenses.

💡 Seller's tip: Don't be afraid of the word "technical." Our in-store teams will show you how to create a realistic fake wound in 5 minutes. It's much simpler than it seems with the right products.

Why should I buy my makeup from you rather than from an online platform?

For health safety. Low-end products on the internet do not always comply with European standards.

💡 Seller's tip: Don't gamble with your skin or eyes. We always ensure quality and compliance with standards (CE/Cosmetic), unlike some foreign platforms. Avoid allergies to save a few cents.

Inspiration Duos & Groups

Do you offer group discounts (student unions, associations, schools)?

More than just a discount, we offer a tailor-made service.

💡 Seller's tip: Contact our dedicated group representative. They will manage quantities and sizes for you so that everyone is served. This is a huge time-saver for organizers.

For which local events do you have costumes?

We follow the French Riviera calendar: Nice Carnival, Lemon Festival (Menton), Bal des Fous (Cannes), White Parties, Halloween, etc.

💡 Seller's tip: Plan ahead! For major events like the Bal des Fous or the Carnival, stock sells out quickly. Come and see us as soon as the official themes are announced.

Quality & Care

Are your costumes washable and reusable (vs Gifi/Action)?

Yes, we are a specialized shop. We have "entry-level" ranges, but also quality ranges made to last.

💡 Seller's tip: Get rid of the "disposable" mindset. Our costumes and wigs are made to be reused, lent, or resold. It's more environmentally friendly and more economical in the long run than buying a costume that ends up in the trash after one night.

Do you offer costume rentals?

No, only sales.

💡 Seller's tip: Let us be your "Personal Shopper." Often, for the price of a rental, we can put together a complete purchase (accessories + outfit). Thanks to our expertise in color and accessory pairing, you'll leave with a suit that's yours and looks just as good.

Store & Omnichannel

Can I view the items on your website (ideafete.com) before coming?

Absolutely. Our website is a (small) showcase of our stock. It allows you to prepare your visit or check availability. Not all of our items are on the website!

💡 Seller's tip: Use the website for browsing, but come to the store for validation. If you have any doubts about a color shade or material seen on screen, nothing beats a real look on the shelf to avoid disappointment.

Are your stores easily accessible from the surrounding major cities?

Yes, we are strategically located to cover the French Riviera.

  • Mougins: Ideal if you are coming from Cannes, Le Cannet, Grasse, or Mandelieu.
  • Villeneuve-Loubet: Perfect for clients coming from Nice, Antibes, Cagnes-sur-Mer, or Saint-Laurent-du-Var.

💡 Seller's Tip: Take advantage of our accessibility. All our stores are located on easily accessible routes with parking, saving you stress before the party.

I have a last-minute emergency before my party, can you help me?

This is the strength of a physical store compared to online delivery (which can be delayed). By coming to Idéafête, you leave with the product immediately.

💡 The seller's advice: Don't risk a lost package 24 hours before the big day. Come see us: even if you don't have an idea, we'll find a solution on the shelf to "save" your costume instantly.
