When family moves in, you expect a few awkward adjustments—different routines, shared spaces, maybe even fridge politics. But for one woman, the friction came from something she never thought she’d have to discuss: her sister’s nightgowns.
After her younger sister moved in post-divorce, the two were mostly in sync—except when it came to what the sister wore at night. Silky, strappy, knee-length nightgowns became a point of contention, and a kitchen encounter in purple satin led to a tense argument neither has been willing to revisit. Here’s the full story and why the internet can’t agree who’s in the wrong.
One woman, living with her husband, asked her sister to stop leaving her room in silky, knee-length nightgowns










Clothing in shared living situations often carries unspoken cultural and personal rules. Dr. Jennifer Baumgartner, author of You Are What You Wear, explains that attire can trigger emotional responses because it intersects with identity, privacy, and perceived propriety.
The host’s discomfort isn’t necessarily about sexualization—it may stem from the “home as a safe zone” mentality, where certain dress codes preserve her sense of control. According to a 2019 Pew Research Center survey on household norms, over 40% of adults reported having explicit or implicit clothing expectations for housemates or guests.
On the flip side, therapist Dr. Rachel Goldman notes that policing someone’s clothing can feel like a challenge to their agency, especially if they’re already in a vulnerable position after major life changes. “For someone regaining independence, even small personal choices—like sleepwear—can become symbolic acts of self-determination,” she says in Healthline.
A compromise—like wearing a robe in shared spaces—could bridge the gap. Etiquette expert Lizzie Post of the Emily Post Institute suggests that in any host-guest conflict, “clarity early on avoids resentment later.” This situation might have been diffused if expectations and comfort levels had been discussed openly from the start.
Here’s what people had to say to OP:
These users call her the jerk, saying the knee-length nightgown is modest and her discomfort reflects personal insecurities





However, these Redditors support her, saying the sister’s nightgown is inappropriate in a shared home with a husband












These commenters back OP’s stance, emphasizing her right to set boundaries in her home



In the end, this isn’t just a debate about silk and straps, it’s about what happens when one person’s comfort clashes with another’s autonomy in a shared space.
Should a houseguest adapt to the host’s sense of propriety, or should the host adjust to the guest’s everyday habits? And where’s the line between a fair house rule and unnecessary control?
