2. Iconic Squid Game Player & Guard Costumes

The Pop Culture Sensation: Fueled by the hype of its new season, this Netflix series costume is back and bigger than ever! It's a super easy and instantly recognizable choice. He can be a determined Player in the iconic green tracksuit (No. 456!) or a mysterious Guard in the red jumpsuit with a circle, triangle, or square mask.

Mom's Savvy Tip: This is one of the best group costume ideas for boys. For guards, make sure the mask allows for clear visibility for safety while walking at night.

3. The Iconic Superhero (Spider-Man & Miles Morales) Costumes

The All-Time Favorite Hero: Let him swing into action in a classic Marvel superhero suit! A Spider-Man costume is always a number one hit. Whether he chooses the iconic red-and-blue of Peter Parker or the sleek black Miles Morales costume, he's guaranteed to feel like a true hero.

Mom's Savvy Tip: Many Spidey suits are one-piece. Look for versions with a separate or detachable mask to make candy-eating and drinking much easier for your little web-slinger!

4. The Mighty Avenger (Captain America & Iron Man) Costumes

For the Heroic Spirit: Time to Avengers Assemble! Let him suit up as one of Earth's Mightiest Heroes. Whether he's defending justice with Captain America's shield or showing off Iron Man's armor, this is the perfect costume for any boy who dreams of being a hero.

Mom's Savvy Tip: The best part of these costumes are the props! A lightweight shield or a simple pair of red gloves for Iron Man can elevate the entire look.

5. Video Game Legends (Minecraft) Costume

From Screen to Street: Bring his favorite game into the real world with a blocky video game costume. This outfit lets him become a character right out of Minecraft, like the main character "MC" Steve. It’s an instantly recognizable choice for the modern gamer.

Mom's Savvy Tip: The boxy headpieces can sometimes limit peripheral vision. For a fun and easy prop, help him make a pixelated pickaxe out of cardboard to carry around.

6. Stealthy Ninja Warrior Costume

The Action-Packed Classic: A favorite for boys who love mystery and martial arts. This ninja costume has everything he needs to become a master of stealth. Many sets can also double as a samurai warrior outfit, making it a versatile choice for action-lovers.

Mom's Savvy Tip: Wear all-black sneakers and a pair of black gloves to complete the head-to-toe stealthy look. It makes a huge difference!

7. Hilarious Inflatable Alien Abduction Costume

The Ultimate Showstopper: Want a funny inflatable costume that will have everyone talking? This is it. This clever optical illusion costume creates the hilarious effect that he's being carried away by an alien. It's pure comedy in a costume.

Mom's Savvy Tip: Make sure you have fresh AA batteries for the fan pack before you leave the house to keep him fully inflated all night long!

8. Glow-in-the-Dark Skeleton Costume

The Classic Spooky Choice: You can't go wrong with a traditional scary boys' costume! This skeleton jumpsuit is simple, comfy, and always effective. This version features awesome glow-in-the-dark bones, making him look extra cool and improving his visibility after sundown.

Mom's Savvy Tip: "Charge" the glow-in-the-dark material by holding it under a bright light for a few minutes before you leave the house for the maximum glowing effect!
