Interracial relationships are more common today than ever before. Do they work? Absolutely! Do they work all the time? Absolutely not! If you are in an interracial relationship, remember to respect your partner's culture.
I (27M) am American, and my girlfriend (28 F) is British and ethnically half-Indian. She is not religious and is culturally very British, speaks with a British accent, etc.
We live in the US and recently started living together. She works at a tech company. I noticed about half the days when she goes to work; she dresses in Indian clothes; even her heels are shiny gold or silver. She looks cute, and I think it is fine for a party or festival, but it looks really out of place for the American workplace.
I have Indian friends in America, and the women dress western here except for festivals. I told her to tone it down as it looks out of place in America, and she might face discrimination, and some of the heels look too unprofessional for the workplace. I work at a bank, and everyone is dressed in formal attire.
