Sidefeel Women's Boyfriend Jeans Stretchy Ripped Distressed Zimbaplatinum Denim Pants Size 4-18

Which size chart should i use?? The one at the top, just below the pictures, or the one beneath the product description? They're wildly different

Does the color the same with picture?

can these be returned?

Can this jeans work with heels? Is it easy for activities?
