The bottom line was that we all looked professional, but in retrospect I worried too much about the exact purse, portfolio, shoe, etc to wear. As long as you look and act professional, you should be fine.
I think this bears repeating.
*Some* of you need real help. * Some* of you are over thinking things. Most of you will be fine.
So while we have critiqued some of your outfits, it's only because we've been asked our opinion, not because the outfit/element was the deciding factor in admission. OTOH, while it's nice to know what others are wearing please don't use that to mean that's what's right.
Suit: matched, no mismatched jackets and skirt/pants/dress. Black is generally considered inappropriate for a business interview but 95% will be wearing it. It's nice to see something different but that doesn't mean red, purple or other bright colors or tan or white. Your choices are charcoal, navy or lighter grey (in warmer months and climes). Pants or skirts are fine. Keep your jacket on.
Skirt length is at your knee or longer WHEN SEATED.
The rules for suits are the same as for men.
Blouse: no wild prints. White is boring and not the most flattering. It is definitely ok to choose color here. Sleeves are best.
Pantyhose: yes; nude or very sheer black. No tights or patterned hose.
Shoes: 2-3 inch heels. Others will be wearing flats. This is not considered professional. No open toes, sling backs, platforms or stilettos. No athletic shoes or boots. They must be darker than your suit and in black, cordovan (if wearing navy).
Purse: small, structured and matching your shoes. Only bring if you need one. Leather or simulated leather.
Portfolio: if you prefer. Bringing one and a large purse looks high maintenance. It should match your shoes.
Earrings: small studs or tiny hoops. No more than 1 per ear and in the lobe (not cartilage).
Watch: if you like; small face.
Other jewelry: a wedding ring or necklace is fine. No jangly bracelets. No political or statement pins on your suit. Remove all facial piercings except 1 earring per ear.
Hair: straight or curly is fine. Keep it tamed and off your face.
Makeup: yes; looks more professional than a bare face.
