the missus wants to wear an aesthetic collar at the club and i think it looks naff... am i being a snob

right ok before anyone jumps on me i know this is a "me" problem. i just wanna hear honest takes. im 41, wife is 38, been in the LS about 5 yrs, mostly clubs around london and a few weekenders in spain through Killing Kittens. she's been getting more openly into the kink end of things in the past 18 months — likes a bit of light D/s with me at home, switches sometimes, the usual. now she's started wearing this lovely little aesthetic collar at the club. like a thin black leather thing with a small ring. she says its just aesthetic, not a "claim", she likes how it sits, makes her feel sexy. and she's 100% allowed to wear whatever she wants obviously. but ngl... i think it looks a bit naff. like every time i see it round her neck i get this little wince like "are we doing this now". its not a jealousy thing, its like a taste thing or a vibe thing that i cant fully articulate. ive not said anything to her because i don't wanna shame her for what she likes. but my silence is starting to feel dishonest and shes picked up on something being off. she asked me last night straight up "do you not like the collar" and i fudged it. so — couples where one of you wears symbolic kink stuff out and the other isn't into the aesthetic, how do you handle it. and is "i find it a bit naff" a legitimate thing to say to your partner about something she clearly loves, or is that just me being snobby and i should suck it up and let her wear what she wants
