A popular way to dress down a pencil skirt is a graphic T and cardigan, or wearing a jean jacket over a cotton top. Also to make is more casual go for a lower vamp shoe.

I look forward to seeing the outfits you put together!

Yup, a cropped little denim jacket was the first idea that came to my mind, too! Underneath you can try a graphic T, or a sleeveless top in one of "your" colors, with or without a print.

I had the same thoughts...the right graphic tee and a cropped, fitted denim jacket. Instead of the denim jacket, maybe a biker jacket with lots of hardwear, in fabric or leather, and that's not black would also keep it casual.

the gals have you covered already with the graphic tee idea! layering with a biker jacket or denim jacket is great too! accessories can also have an impact on an outfit...

for shoes, i think ballet flats or flat boots would look nice, depending on the weather. don't forget the power of tights with boots!

a fun chunky necklace, bangles, or funky earrings can make it a little more carefree and less corporate. you could also try adding a belt- depending on the style of it, it can make the outfit a little more casual.

and finally, scarves can make an outfit more casual too, depending on the material. i'd steer away from silk scarves for a casual look.

ok, let's see some outfits now! :)
