Zulily has a great assortment of Disney-style princess and fairy costumes from just $11.99! You'll also find accessories from just $7.99.
Note that these aren't Disney-brand items, but they're gorgeous and they appear to coordinate perfectly with other well-known princess items at a fraction of the cost!
I'm anespecially big fan of that fairy costume on the left. It even lights up!
Shipping is a flat $7.95, but you can offset that by using Zulily promo code ZU5712 to save $5 on orders of $50 or more.
