Some nice things to say to a woman could include compliments such as "It's nice to see you," "Your eyes look beautiful" or "You have a great sense of humor." Selecting which nice things to say to a particular woman depends on the situation and the existing relationship.
Regardless of the relationship, compliments prevail when searching for nice things to say to a woman. However, if the relationship between the person saying something nice and the woman is a professional one, there are boundaries that should not be crossed. Compliments about a woman's body are off limits in any professional relationship, and even specific compliments about a woman's appearance such as "You have stunning eyes" should be treated with extreme caution. Even if well-intentioned, such comments can be misinterpreted as sexual harassment. Instead, focus on compliments related to a job well done.
Although all people appreciate being complimented on their appearance, it is important to acknowledge that women are not just objects of beauty and to celebrate all facets of their excellent qualities. In a romantic relationship with a woman, there is almost no limit to the nice things that can be said about a woman's personality, her talents or her positive impact on others.
