If you are binary, it may be better to state male or female upfront, rather than to use phrases like “authentic self” or “gender identity”, which could be seen as avoiding the question. They may not recognise terms such as gender identity. You can support your answer with how you have been using gendered spaces in public, and it helps to reassure your employer if you have done so for an extended period of time. If you are non-binary, your answer may depend on the organisation’s work culture and dress code. It may help to think of the office gendered attire simply as a uniform. You are performing a role, and outside of the role you can then be your full self. Such an attitude is common in professional work cultures and in countries such as Japan, China and South Korea. You may feel that you want to be able to express your gender identity at work — you could consider checking with someone working in the company about their office culture. If you don’t know anyone, you could also request to speak to HR or a potential colleague regarding this.
