Dresses and Skirts

  • Dresses and skirts must be no shorter than mid thigh or a few inches above the knee.
  • Slits must not show anything inappropriate and should not be higher than mid thigh or a few inches above the knee.
  • No bare midriffs, holes, mesh or sheer materials in inappropriate areas.
  • No low cut or plunging necklines. When in doubt, test to make sure your neckline is well-fitting at all times as you move without a possibility of slippage. Think: a neckline that would not require the use of double-sided tape.
  • Strapless dresses are permitted as long as they are well fitting and will not slip down.
  • Undergarments should not be visible at all. This includes cover-up shorts under shorter skirts.
  • Avoid trains on dresses as they can be stepped on.

Dress Shirts and Pants

  • No jeans or cargo pants. Dress pants only.
  • Collared dress shirts are permitted, and must be buttoned at all times. T-shirts and tank tops are not permitted.
  • Formal neckwear is encouraged but not required. Examples of formal neckwear include cravats, ties, and bow ties.
  • Suits are encouraged but not required.
  • Undergarments should not be visible at all. This includes cover-up shorts under shorter skirts.


  • The flooring for this event will be carpeting, so please plan accordingly.
  • The following are considered appropriate formal footwear: dress sandals, pumps, flats, some boots, high heels, and dress shoes. Please make sure the footwear does not come off when dancing, or wear shoes with a strap or ties.
    Sneakers, tennis shoes, outdoor sandals, combat boots, and flip flops are not allowed.
    Stiletto or platform heels are STRONGLY discouraged.
    If you have medical restrictions on footwear, please contact ballroom@trickssi.com as soon as you can to discuss options or obtain permission.
  • For further explanation as to why these decisions were made, please read my guide on shoes for formal dances.


  • Cosplay must follow the dress code as listed above. If a fictional or nonfictional character wears an outfit that “almost but not quite” follows the guidelines (a character that wears a tuxedo with tennis shoes), the cosplay must be modified until it meets the dress code.
  • No props that will get in the way. This includes swords, wings, staffs, tails, horns, hats, or guns.
  • Wearing face masks will not be permitted on the dance floor for the safety of all dancers. This includes whole-head latex masks. You may be admitted to the event, but unless you remove those elements, you will be asked to leave the dance floor.
  • Eye patches over one eye are permitted as long as the other eye is unobscured and has peripheral view.
  • Body paint and face paint must be sealed.
  • If wearing a wig, please be sure to keep it secure with hair pins, bobby pins, or a velvet band.
  • Japanese clothing, Lolita, and other Asian formal wear is also welcome as long as it meets the guidelines above.
  • Dress Military Uniforms are welcome as long as they are formal Military Uniforms. Battle Armor and Fantasy Armor are not Dress Military Uniforms and are not allowed.


  • Fursuits will be permitted if attire is dressed over the fur suit and follows all of the above rules. (For example, a fox fursuiter has a gown or tux over the fursuit that matches the formal guidelines.)
  • The only rule that will be waived is the no shoe rule.
  • It is highly recommended that if you wish to dance, you should dance with or very nearby a handler if your headwear restricts your vision in any way.
