Yes, I know about inconsistent sizes. Ordered a pair of boots once on-line. Had bought the same brand several times. Georgia Boot. But they had offshored production to China, huge difference in size. Way too small. And very high heel, hard sole, heel spurs made me almost crippled. I gave them away.
Bought local since then.
I ordered two “one size fits all” hand knitted sweaters from a Chinese fashion store on line. I’m about a 12-14, but love baggy, huge sweaters in the winter with leggings for around the house. The quality was OK on one, but strange yarn on the other that smell like oil lamps??? Neither one of these “one size fits all” fit...were way too tight to wear...bummed. Never ordering Chinese fashions ever again!
