Holly-Rae, 23, not only has hairy armpits herself, she also sees plenty of fuzz when measuring women for underwear.
"It's disturbing that women are criticised for having hair under their arms," Holly-Rae tells Reveal.
"Being a bra-fitter, I see women's pits every day and find it strange when women apologise for not shaving.
"Why are women apologising for something so natural?"
Proud of her own underarm hair, Cambridge-based Holly-Rae admits she was "encouraged" to see Pixie sporting some stubble.
Holly-Rae adds: "I'm surprised by the extremes women go through for the price of so-called beauty.
"I felt encouraged when I heard Pixie had been snapped with hairy pits but, when I looked at the photo, it was no way near as hairy and 'scary' as mine!
"Us Brits really need to get a life and talk about something important."
