As someone who shops at both, Torrid is a godsend for shoes. They have sales and clearance pretty often with a great selection. Also having the shoes come in wide by default is very helpful.
As for ThredUp it's a great way to get good clothes for cheap. It's basically online thrifting. I've gotten some really high end dresses there for cheap. I've only had a couple issues, mainly with an order going missing (which sucks because it was the first time I've splurged on designer jeans) and issues with store credit being issued through a third party gift card service which was kind of weird. While the selection is good sometimes the styles can be a bit "dated" so definitely don't use it to chase style trends.
Over all though both are pretty great and have a good selection!
Ugh, sadly I feel like this is the most accurate answer. So many people don't apply critical thinking to their device and don't even understand they are using a browser to access the web.
