Summer work wear

[BrieAndChilli]

Ok I work in a casual office (so coloured jeans (not blue denim) ankle boots and a smarting top are acceptable but no blue denim, joggers, trainers, flip flops, vest tops etc

I need some nice summer work wear.
Needs to be :
Cheap
Suitable for a pair shaped, size 16 nearly 40 year old
Smart casual

Please find me some outfit as I have NO sense of style!!!

I’m living in chinos at the minute. Slight turn up at the bottom. Silk shirt slightly tucked in. Moccasins. Pretty much my standard summer work wear. So watching with interest!!
