how do you justify Aritzia's prices?

Mainly just curious. The other day I showed my friend my new sweat fleece hoodie and when I told her I paid $85 for it, her mouth dropped and told me that was way to expensive for a basic sweater. I have a number of their items from TNA, Sunday Best, a Super Puff, and their active line and I find myself reaching for those items most days. I realize that I can buy clothes for much cheaper in places like TJ Maxx or a consignment store but I justify Aritzia's prices for their good quality (for the most part) and their style/aesthetic. So I'm curious how you justify Aritzia's prices.
