coming from an ex aritzia girly it depends on what you like best from them, is it the material and "quality" or just how the basics look?
for basics:
- Brandy Melville: it's decently cheap, it's mostly all cotton, it's good basics that come in a multitude of colors, but it's only shirts really
- "mom stores": h&m, gap, black and white, like all those kinda outdated stores that boomers love or you were dragged to for back to school shopping they love basics that are decently affordable and decent quality
for feel:
- cotton-on: I've seen amazing dupes there if the season is right
- garage: its got all those basics, but it's also almost all dupes, think of it as better quality SheIn for aritzia
- department stores: just go to the clearance section there's almost always a perfect dupe for like half off
