where can i get some baggy kinda tapered at the bottom pants/jeans at in size 40
i'd buy big boys or butter goods but they dont make them in my size
A lot of Butter Goods pants go up to size 42, including the Santosuosso jeans, which sound like what you're looking for. The Butter site only has a couple of styles/colours in stock in them right now (if you're in the US), but they make those every season, so I'd just keep an eye out for when they restock.
There's also
these ones from Gap, which are a similar fit, almost $100 cheaper, and go up to 42 as well.
The
Empyre ones from Zumiez go up to 44, and come in a lot of fabric/colour options.
