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!
Is anyone having issues with beehaw? I installed this update and now my heehaw login won't load anything. I can access beehaw from my other instances with no issue.
