These pictures were actually taken last Sunday. And yes, this is my first time to combine two different patterns in one outfit. I think polkadots are such friendly patterns and they look like easily melting together with another patterns. The key is, you need to combine it with another patterns which have similar colours with it. Or you can mix it with another patterns which have the neutral colours, for instance : nude,black,white, and navy blue.
There are just some tips from me about how to use double patterns in one outfit according to my new experience. Hope it'll be useful for you! :)
So sorry for the messy writing. :p
