❌ Business Casual is NOT:

5 Business Casual Mistakes to Avoid
1. Confusing "Casual" with "Sloppy"
Just because it's not a suit doesn't mean anything goes.
Fix: Ensure all clothes are clean, pressed, and well-fitted regardless of formality level.
2. Ignoring Proper Fit
Ill-fitting clothes instantly make you look unprofessional.
Fix: Invest in tailoring for key pieces. A $20 hem can make a $50 shirt look like $200.
3. Overdressing for Your Environment
Being the most formal person in a casual office can be as awkward as being underdressed.
Fix: Observe colleagues for the first week and match the general level of formality.
4. Forgetting About Grooming
Perfect outfit + poor grooming = unprofessional appearance.
Fix: Maintain neat hair, clean nails, and good personal hygiene. These basics are non-negotiable.
5. Not Considering the Occasion
Your outfit for a client presentation should differ from your outfit for an internal team meeting.
Fix: Always consider who you'll be meeting with and adjust your formality level accordingly.
