Another great looking Summer OOTD. We see a bulky white cardigan styled with a white slip tank top tucked in wash blue slim jeans. Complete this combo by adding layered necklaces in gold. The white cardigan, which is a staple of the spring season, has been around for decades. But this year, it seems to be getting more attention than ever. A new trend in fashion that we are seeing right now is wearing white, or at least light blue, with blue jeans and boots. We have seen many variations on these colors before, but what makes them so popular now?
