Boohoo often doesn't have fabric information on their product pages for some reason.
I have tried emailing them about specific items, and I get a reply that they have asked the 'relevant team' and I should hear from them shortly, and then I never do?
If I email back I am again promised they will let me know, and they never do.
Do I assume correctly that it's probably polyester anyway?
They don't want your money then
