Dress Code pour un entretien quand il fait chaud !

While summer can make choosing an outfit more challenging, the expectations for an interview remain the same. The goal is, above all, to project a professional image, regardless of the weather.


So, how should you dress when it’s 30°C without looking careless or too casual? Here are a few simple rules to help you strike the right balance and avoid a fashion faux pas.



Lightweight yet structured outfits


In hot weather, it is perfectly acceptable to opt for lighter clothing. Linen trousers, flowy dresses, midi skirts or cotton shirts are all suitable options, as long as you pay attention to fit and transparency.


The aim is not to endure the heat at the expense of your comfort, but to maintain a polished look that aligns with a professional environment.



Balancing shapes and fits


An outfit often works best when it avoids overly heavy layering. A more fitted piece pairs well with a looser cut, and vice versa.


For instance, a low neckline is best balanced with a more classic skirt or trouser length.


This rule helps prevent any sense of excess that could distract attention during the interview.


Needless to say, crop tops and sheer tops are not appropriate for a first interview!

Staying sharp on the men’s side too


The same principles apply to men’s outfits. A lightweight shirt, worn in a well-fitted cut with one button undone (and no more!), paired with breathable trousers, creates a solid foundation.


The blazer, often seen as essential, can be chosen in lighter fabrics such as linen or carried in the hand if the context allows.


Important: avoid anything too tight. You’re attending an interview, not a bodybuilding competition!

Choosing the right fabrics


Fabric choice plays a key role. Natural materials such as cotton or linen should be prioritised, as they allow better airflow.


On the other hand, synthetic fabrics tend to trap heat and can quickly become uncomfortable, especially in an already stressful situation like a job interview.



Avoiding the overly casual look 


Even in summer, certain items remain unsuitable for an interview:


  • Clothing that is too short;
  • Overly wrinkled fabrics;
  • Beach shorts;
  • Thin straps;
  • Visible underwear;
  • Straw hats;
  • Flip-flops or slide sandals.


Outfits that scream “holiday” are a no-go!


You can show off your style, but don’t forget to remain professional. The recruiter should be able to picture you in the role and focus on your profile, rather than your outfit.



Matching colours


Simplicity is usually the safest option for a first interview. Limiting your outfit to two or three colours helps to maintain visual harmony.


Neutral tones such as white, beige, grey or navy blue are a safe bet, perhaps complemented by a more colourful item, provided you keep it subtle.


For a first interview, patterns are generally best avoided, unless they are very discreet.


Don’t forget to match your socks! Or at least make sure they’re not visible…
