"Picked this up"
"Detail", a generic word to describe some aspect of a garment, as they often have no in-depth knowledge of fashion and a limited vocabulary.
i.e. "So I picked this up in Primark, I really like it, it's got this detail on it here and yeh, I really like it"
Also, not a phrase in particular, but when they are talking to the camera, they all put the most emphasis on the last word of the sentence. I have decided to call it blogger's lilt.
"So today I went shopping and I picked up a FEW BITS, then I went and had a COFFEE, and then took some PHOTOS, and yeh, now I'm going to have a rest".
