I've actually done well in the past on Shein. They have an entire line of very plus sizes! I'm a 3X in the frum stores but a 0X or 1X on shein.
You need to check measurements and you do need to try on tons of stuff and give back what you don't like, but I do that anyway in a store. And there are tons of plus size options!!! I really love it.
Just FYI, re Macy's they've recently changed their retutn policy, everything needs to be returned by 30 days. It got smaller and smaller the window of return which makes it not so easy anymore. That being said, I would so appreciate links I'm also desperate for clothing!!! Thanks!!
