Brown men's XL t-shirt
Multicolor pony beads (I could only find heart shaped, but you can use regular round ones)
So I cut the sides apart, cut strips in them, and tied them together like I'd seen some girls do with t-shirts in high school or like how you make the no-sew fleece blankets. This gave it a more fitted look. I still belted it anyway with a braided rope I had from another shirt I own. I also cut the hem from one of the sleeves to use as a headband - it was the perfect size!
I finished the look off with a braid in my hair, some natural-looking jewelry, a blue tank top underneath, jean shorts, and my brown flats. I did use some safety pins at the shoulders to secure it to my blue tank, and that way it didn't fall down on my arms. Viola!
And seriously...that's it! This was such an easy costume to make. No sewing involved, and the materials only cost me about $8. And who knows, maybe I'll wear it again to a Halloween party or something!
