Given the thread is 18 months old, personally the quality of clothes has changed in that time.
Their summer things (dresses, bikinis) are fantastic.
Shoes I've always loved, never fallen apart and I've worn them for years
Jewellery is so cheap compared to topshop / monsoon and it's fine.
Kids stuff - I brought toddler aged dressed for £8 and they've lasted since March being worn every week and washed on a 30 wash. They're still going too.
Pj's - not the sets but the thin bottoms, I buy new every two years, so they last
Pants/tights - no different quality to m&s if anything, better quality and far far cheaper
Bedding and home wear, fantastic. I've got cushions, towels, accessories - all amazing.
I going only for specific things and don't tend to buy outfits, just one off items. Always happy with purchases.
