Trend #1 is dress shirts. I think they work for formal wear as well as casual wear. You can pair them with almost anything and it'll still look good. There are so many possibilities and I love it. I am especially a big fan of shirts with stripes. These pictures are from Pinterest but I do actually have a few that are quite similar. I love to tuck them into a high waisted jeans, slim fit or mom jeans, it all looks good.
