Plain everyday cardigans.

[WorkingFromHomeShite]

In a variety of colours but plain. Like the equivalent of a comfy pair of jeans, a cardigan you can wear with anything purely as a warm item, not ‘pretty’ or ‘fashionable’.

Preferably under £20.

Or, any specific shops to keep an eye out for cardigans later in the year?

H&M used to do a rack of 100% cotton cardigans in a range of colours.

If you have an M&S outlet store within reach, usually on the outlet villages, they sell them cheaply. I got three for £8 each at the Gretna outlet.

I’ve had great ones from Tu and M&S recently. I hate showing my arms at work and theirs are perfect: wash really well and lovely colours. I think the tu one was £14

came here to say this, m and s is a good place to start.

Primark cotton cardis in menswear. £12. I have khaki, black and navy. Wear them at work and last ages.

Honestly this place is ridiculous sometimes. No one can post anything without the most ridiculous passive aggressive remarks and one upmanship from some posters.

OP, as others have said, M & S would be a good shout. Hope you find what you're looking for.

Totally!

Primark knitwear is good value and washes well. There's not a great deal in stock right now, so you may have to wait until Autumn.

I think TU stuff is usually pretty decent quality and not too pricey.

I like m and s stuff too.

I once managed to get a 100% wool Hobbs cardigan from a charity shop for £10, perfect condition. So I now always have a rummage around the knitwear sections of charity shops. But I'm quite wary about buying second hand knitwear online because I've wasted too much money on items which were really worn looking when they arrived.

Hope you find what you need, I love a cardy!

I buy ALL my clothes from tose places (Temu, too). Some of us haven't got lots of money

@WorkingFromHomeShite
You are very brave asking here! There is for some reason not a lot of love for the things. Mumsnetters clutch at their pearls when you mention them!!!

Yes that's what I meant lovely quality when buying second hand

Tesco have some plain ones at the minute and 25% off with a Clubcard. I can't say how much they are and I only saw black and cream but they looked really soft.

I've found Amazon useful for this.

Uniqlo for sure, merino or lambs wool. They will be more like £30 but wash well and don't bobble, are lightweight but warm.
That said one of my fave throw on while at home cardis is a cheap non wool one from Asda. It's bobbled horribly so not worn out of the house now sadly.

Jump on vinted. You can get some great bargains on there.

Lipsy always seem to have a good range of cardigans.

Bit more than £20 but not too bad

I recommend eBay and Vinted. I buy most of my cardigans and jumpers there these days. Plenty of lovely barely worn (or new with tags!) wool and cashmere. Occasionally have had a bad experience (poor quality, not as described), but still much more affordable than paying full price for new. Happy shopping!

I’ve got myself light grey cardigan with wool from Primark for £8. It’s warm and looks nice.

H & M

Uniqlo and Woolovers

Sorry, just realised you want something under £20. Uniqlo have regular sale items. I've got nice cardis for about £15 in their sake. Woolovers is less likely for under £20 so ignore that suggestion.

I have this in navy. A steal for £12. I'm going to get the white as well. Shame there's no black.

All my cardigans are Vinted now! Brand new M&S cashmere for a tenner etc. Only problem is obvious you have to be patient, spend a lot of time searching etc. Plus you can’t return if it doesn’t fit/suit you. Also need to make sure you check seller reviews but touch wood I’ve had no issues so far!

My tip is to find a style that works for you in a shop then see if you can get it in different colours second hand once you’ve seen how well it wears/how much use you actually get out of it (for example, I like the Hobbs Carrie bolero to go over summer dresses, if I look on Vinted now there are 8 different colour options in my size starting from about 8 quid). I’ve just ordered a Hope and Ivy cardigan for 18 pounds (I have the other colourway which I found in a charity shop last year for 7…).

If you’d rather new then I’d have a look at M&S as other posters have recommended. I’ve had one of their 20 quid cardigans for ages now and it’s still going! It’s not the warmest in terms of it wouldn’t do by itself for a cold day but it’s absolutely fine as an extra layer/is all you need on a warm day.

Thank you for all these recommendations!
