From what i have seen on instagram, all of the top 5 women other than Tasha have got clothing deals with PLT/Oh Polly etc. I am surprised that Tasha is the only one that does not seem to have one. I can see why Ekin-Su and Gemma might have been the top picks for the brands, but i would have expected them to prefer to sign Tasha over, say, Paige, given her amazing figure plus D&I considerations etc.
I know there was a stage when she was not that popular but my impression was that she pulled it back to a large extent whereas Paige's (and even Indiyaah's) popularity waned.
Maybe she is still negotiating hers or is not interested I guess.
