PestyOne
I've stopped buying joggers for wearing indoors in the winter - I've taken to buying the new velvety 'lounge wear' trousers that are sold in the supermarkets.
They're heavier weight, super comfy, wide legged with pockets and draw cord / elastic waistband.
They often have zipped tops, sweatshirts or hoodies to match.
I bought a couple of pairs from Tesco last October and have worn them constantly during the winter months whilst indoors and they've washed really well with no bobbling, shrinkage or colour bleeds.
On really cold days, I've worn thick opaque tights under my 'lounge wear' and have been toasty warm.
PestyOne, I have done exactly the same thing this year. I have bought 3 velvet loungewear suits, 2 from Matalan and one in the sale at La Redoute. They are warm and comfortable and look smart if someone calls round, they have all washed really well.
