I think that there are two ways to wear a "skirt + sweater" combination. One is when a thin sweater is tucked inside a high waisted skirt, and another one is when it isn't. In the outfit that is featured in this post it's my first time wearing it without tucking the sweater in.
Since the sweater is loose, I thought that the skirt needed to be short enough to not create an impression of looking fatter than you really are. This sweater could also go really well with skinny jeans or leggings. I don't wear jeans anymore because I feel like they aren't comfortable enough, but I do wear leggings with jeans print on them.
My favorite part about the sweater is it's texture - it's knit but made of a material that doesn't make you feel hot. And that small pocket on the left is just adorable! As for the skirt, I was thinking about getting a brown/tan colored suede button skirt for a while already, and this one was exactly what I was looking for.
