What to wear to a BCG 1st Round Case Interview?

I wouldn't over think it - wear a suit and tie, and don't over do it. As long as you don't stand out for being badly dressed, you will be fine - no one has ever passed a consulting interview because they wore the best suit.

Hi, I just had an MBB interview and progressed to final round.

Here is what I wore. I was very happy with my choice of attire. Aim to impress and stand out with your case and fit quality rather than your attire - I would avoid the red tie. I feel that if you put in the effort to look great, you'll have more confidence and perform well. Body language is a huge indicator for interviewers and as such; dress code and the way your present is important.

• Navy Suit.
• Brown suit shoes / Brown belt - (Black shoes and navy does not match if you're fussy) Polish the shoes enough so that you can see your nervous face in the reflection (Only kidding!)
• Light blue shirt / Plain spotted navy/white tie
• Discrete watch
• Plain socks

Don't dress too flashy - no cufflinks, Gucci or Rolex type accessories. Don't wear a tie clip either. 

Good luck! 

That sounds perfect - best of luck!

Yes 100% must wear a suit. Keep it convserative and simple. Blue and red are great colors.

Good luck!
