1) Overview


Job attire has changed over the years and with the emergence of tech startup CEOs sporting jeans and t-shirts at the helm of some of the world’s largest companies perceptions have certainly changed.


The global pandemic has also accelerated a move towards more casual work attire as professionals don’t feel the need to be wearing a suit in their own house to talk to clients via video call. This article covers the expected attire for in-person consulting interviews for both men and women as well as what to wear if you are interviewing virtually.



2) Why dressing appropriately is important


There are two reasons for making an effort to dress appropriately for an interview; for yourself and for your interviewer.


Dressing appropriately is a way to boost your own self confidence. Being confident that you are presenting the best image of yourself removes the potential for additional anxiety to creep in when entering the interview. Increasing self-confidence has a direct impact on interview performance.


The second reason to dress appropriately follows the old sayings ‘dress to impress’ or ‘ dress for success’. Rightly or wrongly, the interviewer’s perception of you will be influenced by what you are wearing and there is scientific evidence to support this. In 1995 a study found that people were three times more likely to follow a man dressed in a suit when crossing a busy road than a man wearing a shirt and trousers.


Consultants are providing expertise at a high price to their clients so firms expect their employees to present themselves in a professional manner that meets clients expectations.



3) What to wear - men


There are 5 components covered here for men’s consulting interview attire:

1) Suit

2) Shirt

3) Shoes

4) Accessories

5) Hair



1) Suit


Suits have been the professional uniform of choice for men and women for an incredibly long time. Whilst it is possible to make bold statements with a suit, in consulting neutral styles and simplicity are preferred.


For men this translates into a dark navy or dark grey suit with no stitching or variations such as pinstripes, checks or double breasting. In western culture, black suits are reserved for funerals or dinner suits however in Asia black suits are also sometimes acceptable.


A suit should fit well and meet a couple of simple criteria:

  • The jacket hugs the natural form of the shoulders with no overhang but not so tight that you can’t fold your arms easily

  • The jacket sleeves rest at the point where your thumb bone meets your wrist when your arms are by your side

  • The length of the jacket covers the trouser waistband

  • The trousers rest on the top of your shoes when stood still


Suits are the most expensive component of men’s consulting attire. Appropriate suits can be purchased for around $100 from some high street stores and prices go up to well over $1000 dollars at the top end. For an interview however, you definitely don’t need an expensive suit.


2) Shirt


The second component of men’s attire is the shirt. For consultants and most professionals a simple white or light blue shirt is the most common and suitable for an interview situation. Shirts should fit well, similarly to the suit.


For shirts the most important consideration is the neck size. This is the circumference of the neck when the top button of the shirt is fastened. If the neck is too tight then it will be uncomfortable and if it is too loose it will look scruffy and unprofessional.


3) Shoes


There are a number of styles of men’s shoes from brogues to oxford’s however for a consulting interview the style of shoe is not as important as the colour. The colour of shoe expected in a professional context is either brown or black.

Light brown shoes or tan coloured shoes have been popular in the past but are can be controversial. The best colour option for shoes is black. Black will work with all combinations of suit and shirt plus is considered a smart choice.


The other point to consider with shoes is to make sure they are clean and presentable. It is easy task to clean your shoes prior to an interview and an attention to detail that can positively affect the first impression with your interviewer.


4) Accessories


What you wear beyond the core attire is an opportunity for candidates to express themselves and bring in some of their own personality. The most important accessory is the tie, for consulting it is still expected for men to wear a tie in an interview, you can be more adventurous than with other components but professionalism should still be preferred over fashion and a non-controversial style and colour is best.


Accessories also encompasses watches, cufflinks, pocket squares, tie clips and even aftershave. The general rule of thumb for consulting interviews is to keep these extra items understated. Consulting is not an industry that rewards exuberance and extravagance as consultants are expected to be trustworthy advisers to their clients possessing impeccable rationality and independent judgement.


5) Hair


The cultural expectations regarding hair have flexed and relaxed in recent years with men no longer expected to be clean shaven and sporting a sensible ha
