Dress Code

The dress code sets a minimum standard for attire at school functions while providing room for personal expression. Deerfield values inclusivity, and clothing and accessories sometimes send subtle messages of exclusion; students should take care in these choices.

Deerfield employees are expected to hold students to these guidelines; students are expected to comply when asked to adjust their dress.


Academic dress must be worn (not carried) in the Dining Hall and in all academic buildings during the entire class day—regardless of individuals’ schedules. Academic Dress may also be required on occasions designated by the Head of School or the Assistant Head of School for Student Life.

Students may choose one of two options:

  • Pants/shorts, collared shirt, tie, AND a sportcoat. Shirts must be tucked in, and ties must be visible. (Boys, Gender Nonconforming People)
  • Pants/shorts/skirt and shirt OR dress, AND either a sweater, sportcoat, or jacket (not athletic, fleece, or outerwear). Hemlines must fall at an appropriate length (4–6 inches above the kneecap). (Girls, Gender Nonconforming People)

An “appropriate length” hemline is one that supports full and comfortable participation in all school-day activities. A maximum range of four to six inches above the kneecap is a reasonable guideline.

Blue denim pants, denim jackets of any color, sweatpants, yoga pants, crop tops, athletic attire, and hooded tops are not permitted. Tights/leggings may not be worn without pants/dress/skirt on top. Hats are not to be worn in academic buildings or in the Dining Hall at any time.

All students are expected to adhere to basic standards of hygiene and grooming. Neatly-trimmed facial hair is permitted.

Students are expected to quickly and respectfully accommodate faculty/staff requests to change attire.


  • During winter term only, sweaters or fleeces may replace sportcoats and/or turtlenecks may replace shirt/tie.
  • Casual dress days are as follows: Fridays in February, during end-of-term assessment periods, on vacation travel days, and when designated by the Head of School.
  • Casual dress exceptions for field trips require prior approval of the Assistant Head for Student Life.
  • Students participating in DAPP (the on-campus service program for tenth-graders) must adhere to the academic dress code.

We are eager to support students who have cultural, religious, or gender identities that may not align with our Academic Dress code. Please see your advisor, a member of the Student Life Office, or another trusted adult to discuss alternatives.


Tuesday and Thursday evening meals, and some designated school events, call for “casual dress.” On such occasions, dresses, skirts, pants, or jeans with a collared shirt are appropriate. Sweatpants, leggings, yoga pants, running shorts, printed t-shirts, halter tops, crop tops, sports jerseys and other forms of athletic apparel are not permitted.
