Sometimes you just want to wear something extremely comfy. For me that's wearing shorts, however i'm not allowed to wear them for work, which is a pain but i can work with it. For the summer months i've opted to wear bodycon skirts but i really hate wearing skirts. I've only worn them because it's warm.
For me to change these two outfits (taken from tumblr) unto work appropriate attire, i'd just have to throw on a black skirt or some jeans.
For the first picture i'd change those blue shorts into black skinnies or blue boyfriend jeans and roll the legs up a little so they just hand around my ankle. Personally I don't think a black bodycon skirt would work with this top at all. I really wish i knew where that top came from because that little alien is so cute.
For the second I've already worn something like this for work, it's for one of those days when you wake up and have hardly any time to get ready. With this one I would wear a black body con skirt with it. It would almost cover the skirt completely as the top almost looks dress length. There is no need to change the boots, I would end up wearing the flannel open and not tied around my waist as it gets chilly in the office.
