Mothercare
M+S
John lewis
HELP!
DD has some minor SN and cannot wear synthetics due to sensitive skin but high cotton 80% + is ok. She also cannot undo zips.

TIA

H+M? - wouldn't be "school uniform" but they nearly always have plain basics, like leggings, that could substitute. I used to get all-cotton white shirts for my dd there, for her school uniform. Lasted very well too.

Also Zara, though their clothes are less plain.

I'm nowhere near an H+M
Would need online if poss

I've seen grey leggings in Primark, Matalan and Woolies too - again, not in their uniform section but just as "basics".

Sorry, cross-posted - have just seen your online request.

Have you tried Children's Warehouse? - link is to some trousers that might do, though they seem quite expensive - maybe that's because they are pure cotton? It doesn't say - maybe give them a call? CW is usually a good bet for cotton-rich things.

Does Tesco do any of its range online? Another good basics place.

says only in navy and 3-4 upwards.
Ahh we have scoured all bloody summer and now weather is getting cold tis urgent
Might have to get local sewing lady to whip some up for her...

ta for your help btw Bink :0

shamelessly bumping still no luck at all
