The important thing to note is that you don't necessarily need to wear a completely different outfit each day. For example, you can wear a pair of jeans more than once or you can wear just one pair of shoes the whole trip (as you'll see in my outfits below.) It's all about incorporating the same pieces to make a different look :) The only thing I will be wearing differently each day are my tops, and they're all light-weight.
I've actually assigned an outfit for each day, so 1-4 will be Thursday-Sunday.
Now, I don't know how accurate the weather predictions are online, but I do check the days I will be there and try and plan my outfits around that. Who knows, SF's weather is just as weird as it is in San Diego, but my cousin did say to layer up. If anything, I'll bring my beanie with me when I really need it.
Hope this was helpful!
I'll have a post about my Toiletries tomorrow.
