New me, new look

I've just lost two stone and I am joyfully chucking out almost everything in my wardrobe and am ready to start again - even my boots are baggy now!
I would love some ideas of what the new streamlined me could wear when out walking with my lovely dog who really helped me get fit!
I want a whole new look. What would you buy and from where? I used to hate clothes shopping - can't stop now!
