By using the Costumizer (the little t-shirt icon at upper right).
On any island, select the costumizer tool and click on any charactor and you can choose which pieces of their clothing you want (not all items or appearances can be copied). Also, with poptropica credits that you can purchase or earn by completeting islands (or Earth Day or the Haunted House), you can buy special costumes from the "cool costumes" section of the Poptropica store.
You can also purchase the "Costume Collector" Gold Card for 250 credits or free with membership. You can save up to 3 costumes at once. I believe it is the most worthwhile purchase you will ever make with your credits.
You have to buy a logo.
When you start Poptropica, you can create a new character by customizing their appearance, including selecting their outfit, hair, and other features. After completing the customization, your new character will be ready to explore the various islands and quests in the game. You can also change your character's look at any time by visiting a clothing store or using the in-game customization options. Enjoy your adventure in Poptropica!

Kind of. You can change the color of your Poptropican's skin and hair, though. Skin: Ctrl+Shift+S Hair: Ctrl+Shift+H

No You can't!
You click on the t-shirt in the corner and select the character with the hairstyle you want and then a box will pop up with the characters in it and then you click on the other characters hair and your character will get that hair.
Press Ctrl Shift R and you will change character. Keep pressing Ctrl Shift R until you get the football in your hand.
