It's easy to recreate this look for not too much money. There are a variety of vintage electric blue skirts to be found on etsy.com in the $20-$40 range. For example I like this vintage silk floral skirt ($28).
You can also find more plain options like this longer linen blend skirt ($28) with side pockets.
A pair of bright blue pumps like these suede Steve Madden heels ($70) finishes off the look. You can also find some vintage blue heels on etsy.com.
Pair the skirt with a white t-shirt or an eyelet blouse and you are ready to go from work to evening.
