However, whether he is aware of his actions or not, you cannot let it show that they get to you. Indeed, I think you need to play this as little brother + wife giving you compliments on your strategy. You are their source of inspiration!!! You can mention it sometimes in a affectionately proud way. Just look at you, leading the way, Big Sis. Ignore the small matter that he may have gone beyond you in certain ways. You are not petty like this. No, you are INSPIRATIONAL. Mention that several times a year at family gatherings.
It will help counterbalance the private seething, and may eliminate it altogether.
Me again. I've been on the other side of this. I don't copy anyone, indeed, my SILs have a very different style, but my mere existence is an irritation to them. I'm younger, work less, have a better quality of life, and spend a lot more on my kids than they do. I never post on social media and never gloat in front of them (or bring larger sized versions of their bags to Holidays), but sometimes my husband lets things slip, and I can tell they don't like it.
