Perfectly legit question. Following for inspiration!
It seems harder to find tall ranges stocked in shops so I've never considered a personal shopper as an option.
I'm also tall and curvy and I think the combination makes clothes shopping really really hard. Trousers never have a deep enough rise and tops / dresses never have enough bust room and expect your bust to be really high up your torso.
I wear a fair amount from Oliver Bonas simply because they have space for curves and usually have waists that come up high enough. But everything is too short on me.
I like Lucy and Yak's Addison trousers which have properly high waists, curvy hips and long leg lengths. The plain colours can be styled to look smarter.
