It depends on the context. If it's meant literally as a wife celebrating while naked, it's generally not appropriate in a public or family - friendly setting. However, if it's a more metaphorical use of 'birthday suit' to mean something like being in a natural or unpretentious state while celebrating, then it could potentially be okay, but still a bit strange - sounding.
This is not appropriate in most cases. Since 'birthday suit' commonly means being nude, a story about a wife celebrating in such a state is likely to cross the boundaries of propriety. Even if it's a metaphorical use, it can be easily misconstrued. There are better and more appropriate ways to describe a wife's celebration without using such a potentially racy phrase.
Well, 'in her birthday suit' is an idiom for being nude. So if there's a story about a wife 'celebrates in her birthday suit', it could be a rather inappropriate or just a very unique and private kind of celebration story. However, it could also be a misnomer and not actually mean being naked at all. Maybe it's a creative way of saying she's celebrating in a very relaxed and unadorned state, like without fancy clothes or something.
If it's a story about a wife at a party in her 'birthday suit' (which might mean she's in her normal clothes, not literally nude as that would be inappropriate), perhaps the interesting things could be the unique style of her outfit. It might be a very fashionable or creative look that she has chosen for the party, which makes her stand out and becomes a topic of conversation among the guests.
I think it's his 30th birthday. But you'd better double-check in the novel to be sure.
No, it's not appropriate. A wife being topless in a story, even for a birthday - related one, crosses the line of acceptable behavior. Social norms exist for a reason, and they help maintain a certain level of respect and propriety in our interactions and the stories we tell. It could also make others uncomfortable, whether they are family members, friends or the general public. There are many other ways to make a birthday story interesting and engaging without including such inappropriate elements.
Another great way to surprise her is by arranging a day full of activities she loves. For example, if she likes painting, take her to a painting workshop, then to a nice lunch, and end the day with a movie. Be creative and think about what she enjoys most.
If she looks great in her 'birthday suit' (again, assuming it's a regular, stylish outfit), it can definitely boost the mood. Her positive energy and confidence can be contagious, making others feel excited and happy to be there.
Another story could be about a wife's birthday where her friends throw her a themed party. For example, a 1920s - themed party with flapper dresses and jazz music. Everyone has a great time dancing and celebrating her special day.
Well, typically in the official canon, Harry is not Voldemort's son. Fanfiction, however, allows for all sorts of unconventional storylines. So it's possible in a particular fanfic, but it's not the norm.
Perhaps the story could be that it's a themed birthday party. The 'naked' part could be symbolic, like a 'naked truth' theme. At the party, everyone writes down a sincere and honest message about her on a piece of paper. They then put these papers in a box, and she gets to read them all. It's a unique way to show love and appreciation on her birthday.
Hiring people for a wife's birthday can be a wonderful idea if it's for legitimate services. For example, you could hire a chef to cook a special meal or a photographer to capture the memories. However, if there are ulterior motives that go against the relationship norms, it's not okay.
