The link to the jacket just takes me to a duvet set.
I like the first pink dress - the rest, no so much at all. Being linen to may also want to check that they don't crease really badly. If you suit the style and like them, they do all look like different dresses rather than 4 variations of the same dress iykwim
You might want to start of by just getting one to see how it wears, washes and creases then if you like it get the rest.
