As a guest, can I wear a WHITE skirt & a colored top to an outdoor wedding -or is white a no-no?

Some people say you shouldn’t wear any white, it is reserved for the bride. It will be hot outside and I’d like to wear sandals, a rose colored top and white peasant style skirt. Is this acceptable?

Is it ok to wear a navy top with print navy skirt to casual outdoor afternoon summer wedding. Is navy ok?

The top also has a hood.
