If I’m not thrifting, I buy bottoms from Wrangler. They have men’s and women’s jeans, shorts, cargo shorts, etc. I shop the sales so I’ve gotten jeans starting at $13, they do sales frequently. The quality is always great, shipping is SO fast, I’ve had no problems when I’ve had to return for different sizes. I’m big on denim lasting and not being primarily latex lol, so I love wrangler or vintage.
I love buying vintage denim on eBay primarily, honestly I feel like you can easier find what you want rather than try to hunt it down in the right size when thrifting.
