Go whip up some fun!

"To infinity and beyond!" Become the galaxy's bravest Space Ranger wearing a Buzz Lightyear costume.

A great hero costume from the hit movie Toy Story. A costume as eye-catching as this one will make you very obvious in a party, particularly if you play the part jumping from things and looking for Zorg. Well, don't overdo it, but have a lot of fun!

You could make a Buzz Lightyear costume out of color foam board or painted cardboard. Pick up a picture of Buzz for reference, but it's mostly white with lime green and buttons.

A nice addition may be a laser pointer or led flashlight added to your right arm to represent Buzz' laser.

Have a great time this coming party, with the boys patting you on the back and the girls blowing your whistle!

Hop on the fire truck in a firefighter costume!

Go to that party and save a damsel in burning distress. She needs a hero and who fits this profile better than you in a firefighter costume, a real-life hero. Every woman loves a man in uniform! Don't let them down. Show them how to handle the hose and slide down the pole.

This great costume draws the respect and admiration so rightfully deserved by those brave men that risk their lives to save those of others, but also know how to enjoy life and have fun.

Warriors of the flames.

A Poison Ivy costume will turn you into flora's femme fatale, Gotham City's intoxicating beauty.

Loud red hair, everything else green, leafy and tight, about sums up a Poison Ivy costume. Of course you can stick to the comics original or to the general idea. This is a great choice for red heads, but others can just use a wig or dye.

Funny though, despite she being so popular, the choices of ready-made costumes ir rather poor, but here's a tip: there is an Eve costume that fits the bill, even better than the Poison Ivy ones! Just put away the snake and fruit. Red hair, green footwear and makeup are all that's missing to turn it into an awesome Poison Ivy costume. Two costumes for the price of one.

Poison Ivy is one of the sexiest Batman villains of all time and it's a wonderful choice for that party if you like the character.
