Orange velvet loose sofa covers, large two seater 5-pieces (Westbourne Park W11)

Bought this on Amazon and it doesn't work for our sofa - and they don't want it returned.

Please read the details carefully here for the 'large 3 seater 5 pieces' (which is actually for a large two-seat sofa, hence the 5 pieces, which are 2x seat covers, 2x back covers and 1x large sofa base cover)

It's only been taken out, tried on the sofa, and bundled back up again (for return, i thought).

The fabric is lovely and soft, and very fluid, not like rigid velvet. The seat covers just go over the top with elastic. The large, main cover was too big for our sofa (although you could tuck it in if you have easy access to all the edges. But it is it unlikely to look as perfectly neat and tidy as it does in the listing images.
