BUSINESS FORMAL
If you know what this means, then you’re all set. However, if you need some more guidance to make sure you make a dashing impression at PR Advanced this year, read on:
Basics -
In business formal, dress to impress. It’s your typical office clothing (suits, pant-suits, dresses), but really it’s a chance to get out those classic pieces and spice them up with some of your own pizzazz. Since PR is a creative industry, it is appropriate to be more creative with your outfit while still remaining classy and office-friendly.
General -
Hair
Clean and neat.
Smell
Subtly is the key. You don’t want to shower others with your smell. People more appreciate wisps of your good smell. That being said, make sure you smell good; meaning you are wearing deodorant and don’t smell like smoke.
Fit
Clothes should be fitted. Not baggy and not too tight.
Women -

Skirt/Dress Length
Your skirt/dress should come down to your knee while you are standing. When sitting, your thighs should be covered. If your skirt/dress goes just below the knee, it is fine for a slit to go slightly above the knee. However, long dresses/skirts should no have slits above the knee. In business, slits are to facilitate walking and climbing stairs, not to show off your legs.
Shirt/Sweater
Like tailored shirts of blouses, a tailored sweater can be a nice addition. Try to avoid velvet and shimmery fabrics that you would wear to parties. Instead, cotton, silk and blends are better options. Fit should not be tight.
Jewelry/Accessories
Again, since PR is a creative field, you can definitely have fun with your jewelry and accessories. However, don’t go overboard. Keep it classy.
Cosmetics
In general, stick to a more natural look. But still have fun and make it you.
Shoes
Most importantly: BE COMFORTABLE! The last thing you want to do is hobble around the career fair at the end of the day because your shoes were too tight or too tall. Close-toed shoes that coordinate with your outfit are the most appropriate. This is definitely an area where you want to fuse fashion and function.
Hose
We recommend that you wear them with skirts above the knee or if it is cold/snowy/rainy outside.
Purse/Bag
Keep it simple. A structured purse looks more professional than a floppy one. As you know, your purse should coordinate with your shoes. For a some great suggestions as to what you should carry in your purse, go to wardrobeoxygen.com
Men -

Suits
Business formal means business suit. It doesn’t necessarily have to be a matching three piece suit, but make sure you have a jacket and nice slacks. Do not show up in jeans and a denim jacket.
Ties
A tie is necessary and such a great way to add your own element. You can go skinny or large, patterned or solid, loud or subtle.
Shoes
No sneakers. You do not necessarily need to wear shiny polished shoes, but it is important to wear nice shoes. Leather or suede is preferred. Also, you do not have to stick with normal shoes, some business casual outfits would look great with a pair of nice boots.
Facial Hair
Your facial hair should be nicely groomed. Scragglyness is not appropriate. It doesn’t matter if you have a beard, mustache, or nothing, just make sure you look clean and maintained.
