You can not only look at the clothes but also the hair. It's done like you don't care. A bit frizzy and wavy. Like you have washed it but have not bothered to comb it.
If you look really closely to the picture with the blue dress then you can even see that she has a nude colour nail polish on her nails.
Just as I thought we left jumpers laying in the winter closet it seems to be that they are coming back with even more patterns on them. For example you can dress it with shorts or in this case with a skirt. This is perfect for cold spring days. Like the weather on the weekend which was terrible in the UK.
