I think Torrid might still be your best bet when it comes to consistent inventory, just judging from my other half’s experience. What’s Shein?

Shein has ok quality clothing at reasonable prices. Really only go a 3X. Younger looking clothing. Very cute lingerie.
There are stores on eBay that are jobbers They QVC and HSN and sell their leftovers at ridiculously low prices. They are hit and miss but go up higher in sizing.
Message me for a list of them I’ve found so far.

Shein is pretty consistent… just consistently small. Always order a size up! The good thing is they have a lenient return policy so I’ve never had a problem returning anything. I’ve also found Nordstrom Rack to be really great! They don’t carry much plus in store but there is so much online for really decent prices 😊 the eBay comment also made me remember Poshmark

Haven't checked it out in person yet, but Old Navy has been advertising that they are now carrying up to (IIRC) size 28 in store -- with no little 'plus size' section tucked in the corner, all sizes of all clothes in the main racks. Might be worth checking out for cheap stuff.

I can related to that, but unfortunately it's incredibly hard, if not impossible, to find niche fashion in larger sizes 😢

For more normal stuff, I've found onestopplus.com to be decent enough, and they usually have sales or coupon codes (use Google to find them) that give nice discounts.

I shop at WOMAN WITHIN, LANE BRYANT ,CATHERINES, ROMANS.
