If you're a shopper like me, you should pack the bare essentials and then shop like mad in Shanghai!
Otherwise, Shanghai weather can be unpredictable. So, layers is best, especially since most indoor places will be either heated or air-conditioned.
In Shanghai winter, you will need a warm, padded or feather-down jacket to keep you warm while outdoors. While its summer can be scorchers with plenty of humidity, so t-shirt and shorts. I always recommend closed shoes, no matter the weather because of the questionable cleanliness of public restrooms! :)
