I just found a really cute pair of black J Brand skinny jeans with contrast stitching. I love how the semi stretchy material hugs my legs and calves...except the waist is too big! They didnt have my usual size in stock so I found it in a size bigger. This was the only pair I could find so they didn't even have a size smaller to try on. The waist is big enough that I feel self conscious when I sit. It's maybe a couple of inches loose in total. I definitely do not want to sport a Plumbers Crack. Will a belt help this problem or should I just return the jeans? If a belt will work, what kind of belt??
