90% office based, small family run company in the construction industry. What would you wear? Starting a new job. Currently one other middle aged lady plus boss in the office, other lady wears jeans/trainers/jumpers. Boss wears jeans/boots/casual shirts (think work men) type attire. Would be in the office most of the time but once/twice a week going to building sites for meetings. Don't think heals and skirt going to be appropriate but also don't want to go with jeans and trainers. any suggestion?
