Camo and Floral...
Camo is great for mixing prints because it is subtle and cool on it's own. It doesn't take away from the floral but it elevates it. LuLa Roe makes great floral dresses, this one is a Carly. Pick a bag in a complementary color so not to distract from your pattern combination.

Complementary Patterns...I picked a LuLa Roe Carly and Leggings in a very similar but not quite the same pattern to mix together. They also have similar colors which helps them gel. This look is fun so it needed fun accessories.
