Now that I've reached legality worldwide though, I can't seem to get enough of it. I've already bought this J Crew cardigan in both colors shown above. I've even raided my mom's wardrobe for cardigans and found some gems like classic Vivienne Westwood and Ralph Lauren twin sets in a navy, gray and pink. They are the best staple a girl can have. It can be by itself with black pants, for a casual office look, Or with jeans for a casual but put together look. It can be worn over something pretty but sheer or summer dresses, to keep the chill away. 
And it can paired with printed tees (like the ones above from UO- I LOVE these two printed shirts, one of the few things from UO over the years that I absolutely adore) or bold colored tanks for a fun combo. I personally love these two last ideas, it is put together, sophisticated but still casual and fun. And here's a quick tip: pair the blue printed tee (above) with the white cardigan and the red printed tee with the cobalt blue cardigan.The printed tees by itself may possibly be misconstrued as waitress-like (seriously, I tried mine on and that's what my cousin told me I reminded her of). But in combination with the contrasting colored cardigans that doesn't take away from the design, it is the perfect mix and match combo.I'm so glad I rediscovered these gems that I'd previously discarded!
