Did somebody take my name in vain? XD
Hi Christie! I find myself in a position of odd imbalance: I work in the industrial plant of a mushroom farm and I do more plant maintenance/operations than office/corporate.. but I also do a lot of meetings and seminars and must be prepared to change hats (and clothes) at a moment's notice!
If I'm going to an off-plant meeting, seminar or trade show, I dress in full corporate gear. I found that if I wear a skirt - even a business suit skirt - I get treated like a 'lady', but not acknowledged as an engineer. So I wear slacks, a simple blouse and accent scarf, and a suit jacket, and I wear my hair in a French twist. As HgTX suggests, I wear 'natural' makeup. Dressed like this, people seem to see "engineer" first, "woman" after. Some people still treat me like Zaphod Beeblebrox, but most people just treat me like any other engineering professional and once we start talking shop, the love of engineering melts all other differences :B
For interviews, I dress very much the same way, only I make sure that everything I'm wearing is machine washable. If I can't peel it off and chuck it into the washer, I don't wear it. This is because I never know exactly what I'll be doing, and quite often a plant tour is involved -- so safety shoes and a hairstyle that fits under a bump cap are wise ideas.
On site, even the office area of our plant is very dusty and prone to dirt. Washable slacks are suitable here, and tidy jeans and shirts are considered quite acceptable here, especially among the maintenance office staff. In the industrial plant itself, rubbies are the norm for maintenance and compost personnel, as they are always hidden by coveralls. 70% of the time, I'm in the plant and hidden under my coveralls. Unfortunately, my coveralls are baggy and shapeless and make me look like a 6 year old playing dress-up -- not too professional of a presentation XD So I always have a clean labcoat-style of coverall handy: If a sales rep drops by or an unexpected meeting is called, I can jump out of my baggy suit and pull on my labcoat. The labcoat makes a dramatic difference in professional appearance (people start calling me "the Doctor" whenever I've got my labcoat on XD ) Its instant respect, so I recommend having one - check with whomever supplies your coveralls.
Our plant is a food growing/processing plant, so OSHA regulations forbid makeup, which makes my morning easier XD Contact lenses are also not a good idea here, as there is so much dust (gets under lenses and scratches corneas) Again as HgTX pointed out, jewellery of any sort (rings, earrings, necklaces, toe rings, piercings, etc) are safety hazards, from both electrical and mechanical standpoints. If your hair is long, wear it in a topknot, a low chignon or bee-butt bun, or a French twist: These styles fit under hard hats and bump caps, keep all of the hair out of mechanical and chemical risk, and look professional when you take your hat off for a meeting. I don't recommend a braid because the braid can still swing around and get caught in machinery or dunk itself into chemicals; wear a braid only if you know for sure that you won't be anywhere near any kind of machinery. Forego the fancy hair sticks, French twist combs, Ficcare clips and other embellishments if you know you're going to be wearing your hat - they'll get damaged and pose the same risks as other jewellery. If you know you won't be wearing your hat at any time during the day (seminars, trade shows, etc), then the hair jewellery is great. If you can't find dressy-looking steel-toed shoes in your size (lord knows I can't), then don't worry about it: Steel-toed shoes are always acceptable industrial business attire, no matter how scuffy they are. If you're doing a lot of transitioning between the office and the plant, wear your steel-toes and your hard hat. Even if you're wearing a suit. Attention to safety is the most professional image you can project, so choose safety first over spiffy - coz with Murphy's Law, the day you choose spiffy is the the day you lose toes >.<
Your situation is no doubt very different from mine, but I hope this helps a bit. Congratulations on your promotion, Christie, and good luck
