For this school year we have a newly-aligned and consistent set of rules for uniforms across all grade levels.  In keeping with recent years’ modifications, students are allowed to wear either the yellow or white golf shirt during any season.  

Winter Uniform      

  • The winter uniform consists of the MMA blazer, plaid kilt, yellow or white golf shirt, and a brown Oxford-style tie-shoe or brown Sperry.
  • If/when a student is not wearing the blazer, a navy MMA sweater (with red piping) or the official (uniform) MMA fleece must be worn during the winter season.
  • Navy tights or leggings are required to be worn with the winter uniform.
  • White crew socks should be worn with the leggings.
  • The plaid kilt should be no more than 4 inches above the knee.
  • The brown shoe must have a full back, a firm sole, and heels no higher than one inch.  They must also have laces and tie.  The shoe should not have a patterned design.  It may not be a moccasin slipper, boot, or sneaker-type shoe.  A brown leather Oxford, a brown Sperry, or a brown suede buck style shoe is recommended.     

Fall/Spring Uniform

  • The fall/spring uniform consists of the khaki skirt and a yellow or white golf shirt.
  • The khaki skirt should be no more than 4 inches above the knee.
  • If a t-shirt is worn under the school golf shirt, then it must be all white.
  • Tights or leggings are worn in the fall and spring when the weather is cool (as determined by the administration).
  • The school sweater, fleece, or blazer may also be worn if/when the weather is cool.
  • The brown tie shoe is worn with only white socks that have a cuff of at least one inch; no colored socks are allowed.

Blazers must be worn for all formal events: school liturgies, prayer services, and assemblies.

Gym Uniforms

  • For gym, any Merion tee-shirt is acceptable, and any shorts even if they are not MMA branded. The Spirit Shop has a variety of tee-shirts and shorts available for sale.

Pins on Blazer Lapels

  • All pins must be Merion Mercy related or relevant.
  • They must reflect association with a student’s most recent activity or sport.
  • The maximum number to be work on a blazer at one time is 8.
  • Special ad buttons and commemorative ribbons may only be worn during the week of the show or activity/event. 


  • A student may only wear sneakers if she has written permission from a doctor stating the injury (or need for accommodation) and the forecasted time for recovery.
  • Whenever sneakers are worn – for approved medical reasons or by decree of the administration – they must be white, black, navy, or gray.  No exceptions are made for outlandish colors and/or designs.
  • Seniors are permitted, as a privilege, to wear college sweatshirts or MMA spirit gear (sweatshirts or fleeces) on Fridays.  When doing so, they must wear a uniform golf shirt underneath.  Seniors are not permitted to wear other high schools’ sweatshirts (with their logos, etc.).
