She still can’t fit into itI think it's more that they claim to be size inclusive and only go up to mid fat sizes at most, rather than what size they actually go up to, and bang on about it in their marketing. Just don't mention it, or say "we go up to a 24" or whatever.
And with the influencers, it seems to be if the store stock their size, they're all over it. Look at Poppy Adams promoting Peacock and saying how amazing it is they do plus sizes when 6 months ago she wouldn't have fit into anything they sell.
I genuinely didn’t think there were any sizes after a 32I don’t think she looked very well in that post. Also, what sizes should brands go up to really? If they really were inclusive they’d have to go to size 44 or something and that’s not good for business
