Context: I'm a 37F who wears a size DD bra. I'm otherwise short and petite, making my chest look even larger. I also have a large scar on my chest from a life-saving surgery I had as an infant. I like to show my scar bc I think it's really badass that I survived such a complicated surgery so early in life. I like to talk about my scar, my surgery, and my condition with others, bc I'm a survivor and not every infant who had this surgery lived to talk about it. I have a much younger sister (almost 10 years between us) who has 4 kids that I absolutely adore, all under age 8. Last time I visited them, I wore a sports bra and tank top. Inevitably, this also showed some cleavage. My sister texted me recently to invite me to my nephew's upcoming bday party...and to ask me "Can you just do me a favor- no more low cut shirts around the kids please. Thank you." Most shirts give me cleavage! Unless they're hoodies or unisex t-shirts, there's going to be a bit of cleavage. I really don't know how to respond to this request. I wasn't wearing anything super sexy - just an old sports bra and a tank top, so I could play with the kids easily on the playground. My sister is extremely conservative/religious. She converted to a very strict Catholic church as an adult (we were raised Pentecostal). I know that's at least part of where this request is coming from. The other part is that while I was visiting her kids, her 5yo son tried to nurse from me while I was trying to get him to nap. Like, he reached into my sports bra and pulled out a boob 😬 I was super freaked out and told her about it right away! She said that they sometimes like to "play at nursing," whatever that means. The 3yo also kept touching my chest and asking if there was "milk in there." I don't know how to respond to my sister's request. It would be difficult to do, but not impossible. But I'm also worried about her putting more and more restrictions around what I can and cannot do around her and the kids. She also recently asked me not to say things like "oh my God" around them, because she feels that's a form of swearing. There are other weird things that she's asked me or our parents to do as well. (Another example: they're no longer doing "co-ed swimming," as she calls it, even if it's just with family). AITA for being proud of my scar? Or for showing cleavage at all? I don't want to risk the delicate relationship I've been rebuilding with my sister, but I also think it's important for her to understand that I'm not just showing off cleavage. To me, my surgery scar is a battle scar, and it reminds me how lucky I am to be here at all.
