I recently bought the J.Crew Cotton Corsage Cardigan in mint green (for some reason this color is not available online). I'm wearing it today, but this piece can be taken into Fall (obviously, since it was part of the Fall line).
Today I summer-ized (a bit, b/c my office is pretty cool) this cardigan.
Wearing it over an American Apparel deep V-neck T-shirt in evergreen
An A-line, slightly fuller khaki skirt I got on super sale from Ann Taylor Loft, but is no longer available. This Old Navy skirt has the same idea.
I topped the skirt with a thin silver belt, similar to this one from Amazon (and only $2.75!).
The flats I'm wearing are last years yellow and gray ruffle flats from Target (shown in picture), however, they are no longer available. But these yellow peep-toe bow flats are a cute alternative.
To bring this cardi into Fall, just add more coverage.
Once the weather turns a bit cooler, I'll pair this mint cardi with my favorite-fit everyday chino in golden cypress (that I got last winter when they were full price...now they are only $19.99!!!). I'll wear it over a lacy or subtly embellished ivory cami (I have one from JCrew - that is also not online, for some reason, that has little horizontal ruffles down the torso). Rounding this look off with the same skinny silver belt and silver/gray shoes.
For the winter, adding pashminas, a cute code and some gloves and you're set!
See Gigi modeling this cardigan as well!
