Why Dressing Professionally Matters During Your Internship.

Internship Dress Code: Key Rules to Follow.
Do Wear Closed-Toe Shoes.
In most office environments, sandals are not considered professional. Stick with dress shoes or flats. Keep your footwear clean, comfortable, and closed-toe.
Don’t Wear Sportswear.
Jerseys, baseball caps, hoodies, and athletic sneakers are great for weekends but inappropriate in most office settings. Aim for a neat, polished look instead.
Do Rock Business Casual.
While business casual may seem a bit plain, it’s versatile and safe for most workplaces. Think slacks or khakis paired with a collared shirt or blouse. Personal flair is great, but stay within professional bounds.
Don’t Show Too Much Skin.
Especially during warmer months, avoid clothing that's too revealing. Shorts, tank tops, and short skirts may be comfortable, but they can come across as unprofessional.
Do Dress for the Job You Want.
Even in a laid-back office, dressing one step above the norm demonstrates ambition and professionalism. Your wardrobe should reflect that you take your role seriously.
Don’t Overdo Casual Fridays.
If your company observes Casual Fridays, maintain a level of professionalism. If you have meetings scheduled, it’s always safer to dress up rather than down.
Do Keep Clothes Clean and Wrinkle-Free.
A crisp shirt or blouse can still look sloppy if it’s wrinkled or stained. Make sure everything you wear is clean, pressed, and fits properly.
Don’t Go Overboard during Holidays.
Holiday spirit is great, but keep it subtle. A red sweater or seasonal accessory is fine, but skip the blinking earrings or novelty ties.

Use your supervisors and office managers as a style reference. If they lean more formal, follow their lead. It shows you’re aligned with company culture.
Don’t Wear Flashy or Distracting Items.
Avoid anything that pulls attention away from your work. That includes loud patterns, glitter, flashy jewelry, and excessive makeup.
Do Consult the Employee Handbook.
If you're unsure about what's acceptable, your company’s employee handbook should be your first stop. Review it before your first day to make sure you're dressed to impress from day one.
