Now if you're like me at all, the denim-on-denim trend scared the bejesus out of you. However, this new trend is not about mom jeans with an acid wash top. This trend takes denim and makes it chic. If you are going to go about this look, opt for an oversized denim shirt and skinny or wide-leg jeans. The only rule for this look: make sure that the two pieces are DIFFERENT washes of denim, otherwise you will wind up looking like that 90s taboo.
