Meanwhile, another shopper also pointed out the similarities to Chanel, they said: "It looks like a Chanel and goes perfectly with jeans, navy pants or skirts.
Not everyone was totally obsessed with the piece though, as someone else said: "The cardigan looks good but is a bit shapeless because of the material which makes it quite heavy.

Is supermarket fashion the new high street?
DEPUTY Fashion Editor Abby McHale weighs in:
The supermarkets have really upped their game when it comes to their fashion lines. These days, as you head in to do your weekly food shop you can also pick up a selection of purse-friendly, stylish pieces for all the family.
Tesco has just announced a 0.7 per cent increase in the quarter thanks to a 'strong growth in clothing' and M&S has earnt the title of the number one destination for womenswear on the high street.
Asda's clothing line George has made £1.5 million for the supermarket in 2023, 80 per cent of Sainsbury's clothes sold at full price rather than discounted and Nutmeg at Morrisons sales are also up 2 per cent in the past year.
So what is it about supermarket fashion that is becoming so successful?
Apart from the clothing actually being affordable, it's good quality too - with many being part of schemes such as the Better Cotton Initiative.
A lot of the time they keep to classic pieces that they know will last the customer year after year.
Plus because they buy so much stock they can turn around pieces quickly and buy for cheaper because of the volumes.
