I think New Trier is one of the few public highschool’s that requires those who don’t want to wear dresses/dressy pantsuit (white) to wear a tux!
These used to be called Male and Female requirements but now they just do it by type of dress:
Must meet either “Dress/Formal Dressy Pantsuit” guidelines or Tuxedo guidelines.
Dresses must be mid-calf or longer in length
Dresses must be white or off-white with all-white details (no sequins or colored accessories)
The bodice (chest and stomach) and back (up to where the bra strap would cross the back) must be covered. No cut-outs in these areas
Shoes can be white, off-white, or nude in color. Shoes must be dressy, either flats or heels (no flip flops).
A formal dressy all-white pantsuit or jumpsuit may be worn as long as it meets the same guidelines above
Tuxedo Guidelines
White tuxedo coat with black trousers, white shirt, black bow tie, black socks and black shoes
All tuxedo items may be rented at local formal wear stores.
