Some help on picking stuff....

Hi everyone! I'm going to a lolita theme baby shower and I have a little doubt about my outfit.  I haven't worn a full lolita outfit since a longtime ago.  I'm not sure if the cape goes with it or if I should wear something else.


this is the skirt


they are not purple, they are solid white. For some weird reason the walls make them look that color


the blouse

and finally, the cape


thanks for the help I can get, Love miso~soup
