I have this blue (gray blue) blouse for long time and could not style it, but finally I find a solution with white kick flared ankle jeans.Last week I
went to a concert of Renaissance music in the Ethnographic Museum and I wore this blue and white combination: blue blouse and blue bag, white kick flared ankle jeans and ballet, long necklace white and blue and necklace with pendant, and earrings.

Thanks for all comments and suggestions.
