My younger sister often stays with us for a few days at a time as she lives fairly far away and we like to spend time together and have always been a close knit family.
The last few times she's obviously getting more and more comfortable and has starting coming downstairs in the mornings and evenings wearing her, really quite skimpy, pj's. I guess they could be described as lacy hotpants and a crop top. She's now even go as far as strolling around in just her underwear after her shower!
I have no insecurities about my husband being interested in her or checking her out but for some reason I am finding it a bit uncomfortable. Am I being unfair to consider asking her to at least put on a dressing gown? The most I've said is along the lines of "aren't you a bit cold in just that?" but she obviously didn't see it as a hint and continues to do it.
Is it really too different to her being in a bikini when we're all at the beach or does it cross some sort of boundary? I know that if I did bring the topic up she'd laugh it off and tell me I'm being a prude and genuinely not understand what the problem is. Maybe it isn't a problem and it's something I need to get over? I just don't know.
