Scenario 1...

My first scenario is a 20 year old woman, size 16, hourglass figure, going to a job interview in banking...

High Waisted Wide Leg Trousers form Next £28
Georgette Pussybow Blouse from ASOS £28
Patent Twist Strap court from New look £24.99

I have chosen this outfit for my first scenario because the high waisted trousers show off the hourglass figure well, by outlining the curves of the hips.
The heels with the wide legged trousers will elongate the legs and make her look taller and slimmer.
The pussybow blouse adds a pop of colour to a sophisticated look
