Cottages. All the teeny-meeny windows, oppressive looking beams, low peasant ceilings, cutesy cutesy quilts, stone, old 'cozy' fireplaces, rocking chairs, granny chic. Nothing that can be described as 'cute and cozy'. I don't want to live in the 'Wind in the Willows', ffs.
Arts&Crafts. Similar reasons. Fusty, musty, old-fashioned. Just because it's old, doesn't mean it's good.
Shabby chic.
Solely British thing - carpet EVERYWHERE. On the stairs, in every room, in extreme cases even in the bathroom. Just...why??? So naff and pedestrian.
Not a trend anymore (hopefully), but crushed velvet, mirrored furniture, crystals, fake D&G towels/bedding - WAG chic.
Obv all the 'live, laugh, love' signs.
Those disgusting poofy, reclining, bulky leather sofas/armchairs.
Low/regular ceilings (has to be high) and small windows.
No sockets in bathrooms. All the rest of the world manage somehow..
