Wintertime is Arizona is the best. It feels exactly like fall in the midwest. The leaves start to fall off the trees (FINALLY) and the air is crisp. The most you need to wear is a light jacket or sweater or, in my case, a cape to stay warm. I got this beautiful cherry red cape from ChicWish last year (try this grey one), but this is the first time I have worn it. It got shoved into the back of my closet and I completely forgot about it.
Since dusting it off, I have received so many compliments on it. You can wear this cape with or without a belt. I like it with a belt so that my waist is defined. I paired it with a patterned shirt so that my whole outfit wasn't color blocked.
Try out a cape if you find one you like. It's a unique and stylish alternative to your trusty sweater.
