If you're looking for some oversized shirts for the gym then I recommend the Dazy shirts on Shein. They're better quality than Shein's other shirts. Only thing is that they do shrink in the dryer so sizing up would be a good decision.
I don't remember the exact leggings I got, but all the black leggings on Shein are basically the same lol. The leggings fit me perfect! Not tight not loose. They are comfy to workout in (or run errands if you desire) 🤞
