Bests & Worsts Reviews from Amazon

I normally wear a US size 7, so I ordered a 7/8, and they were way too small (my heel hangs off the back of them). The color I received is also MUCH darker than what is pictured. I figured I’d just return them and size up/see if I get the correct color , but when I tried to return the first pair, in order to return them I’d have to mail them back to China and pay postage (which would cost more than the slippers). So now I’m stuck with slippers that are way too small because I have no way of returning. Just FYI, if you are in between sizes, size up because if they don’t fit, you won’t be able to return them.
