This top was from Old Navy a few years back. It's been washed so many times now it feels like wearing a blanket. Super comfy - but it's wearing out - and I've been on the lookout for a replacement. Maybe this, this, or this.
Pants are the Faded Glory brand that Walmart carries in the states only. I recommend if you are shopping across the border that you check out Walmart's Faded Glory brand. It's fairly casual but there's some good basics pieces. These are jeggings that I have in 3 colours, they're super stretchy but have pockets and a fly like regular jeans.
Payless here or you could try these ones here
Have a great day.
