A few years ago I used to try to watch Chase Amie not because her style is at all interesting but because she had a couple of reviews of bags I thought I might like. But the way she talks straight through every video without ever once taking a breath of air drove me bananas. I was never interested in her promotions/recommendations.
These are the ones I tend to trust (if one can speak of trust in any online scenario) and that's not to say I'd go out and spend money on something just because they recommended an item or flashed a coupon code; it's that they each seem real (in their own way) and straightforward, and at least one facet of their style/wardrobe overlaps with the stuff I like:
I enjoy Sophie Shohet for her genuine personality and comforting manner. Wenwen Stokes has an ecclectic style and always has some unusual finds to show. Cassie Thorpe is an absolute hoot, her sense of humour cracks me up. I still watch Lalli Mirza, Tamara Kalinic, and Claire Chanelle just because their life$tyles seem so decadent. Style Hard is down to earth and I like her high-low mix of things. Jonathan Lucca is rather new to YT, has a nice bag collection and sweet personality. KarenBritChick is another enjoyable personality, and I've been a year-long follower of Lissy in the City, a real person in my age bracket I can relate to.
[OT: not an influencer but highly recommended: the best fashion commentator on YT imho is Loic Prigent. His long videos are an absolute treat and researched in great detail.]
