Smart work trousers. Help!

[GooodMythicalMorning]

Started a new job, (small hippyish type shop.) we are allowed to wear our own clothes but no jeans, trainers and hoodies which I what I was living in. Am 30, 5"10 and a fairly trim 12 on top but 14 on bottom cos I have wide hips. Im completely stuck on what trousers I should get as I want something smart but doesnt look like school type trousers. Also cant be too expensive. Thanks. (Any other clothes suggestions are helpful too!)

Chinos? Next have some colourful ones in at the mo. can dress up with smarter sandals/shoes or down with converse/Birkenstocks?

Think they were about £20?

Im not really sure what chinos are but will google. Thank you. Thats the kind of price I was thinking.

Patterned cigarette trousers would be smart but more interesting than black trousers for a casual shop. Choose a small print for a more flattering look on larger hips. Then you can team with basics like plain black or grey tops. Heels, sandals or flats are all good.
