Cute, comfortable and stylish jeans
Size: Small, Color: Blue
These jeans are so cute! They are on the thicker, stiffer size. I got a lot of compliments on the patchwork jeans. They did arrive with a very strong sort of chemical odor. I washed twice before I wore them.

Perfect for casual wear and dressy style
Color: Dark Green, Size: Small
This sweater is soooo soft and the color is so rich. The fit of it is perfect, not too tight and not too baggy, just right and I used the size guide to pick my size. Just for reference, I am 5'3" and 130lbs, 38C bust. It's well made and washes great. I chose to hang dry mine as I typically don't put any of my sweaters in the dryer to dry, just to fluff them. I have this one in two colors, the green and the tan/beige and I would say they are both a true representative of the color shown.
