Is it haram to sell Luxury items?

I own a instagram page in the luxury niche. I run this page to sell luxury items (like watches & etc.). I know islam doesn’t encourage you to live a luxurious life or waste money on worldly things, rather donate and help the poor! I really don't want my business/income to be haram. I don't post any haram content on my page (i.e. music, women, nudity). I usually would be posting pictures & videos of cars,watches etc. Will i be sinful to run a business like this? Please answer wisely! May Allah Bless You & keep your family healthy & safe <3
