I found the USAG guidelines but I don’t know if it’s very helpful- what “deliberately exposed” means seems dangerously and deliberately vague. Are there any judges able to weigh in?
“ Presentherselfintheproperattire.
a. Allowable apparel for competition in both Women’s programs (Development (Dev) and Xcel):
1) Sleeveless leotards
2) Unitards with ankle length legs
3) Ankle length tights: may be worn under OR over the leotard (that match the leotard or are skin tone).
4) Gymnastics footwear
• Tennis shoes (athletic sneakers) are NOT considered gymnastics footwear.
5) Shorts: must be solid black (small manufacturer’s branding allowed) with no embellishments.
Shorts must be worn over a leotard and the length must be above the knee or shorter.
b. After an initial warning, a 0.20 deduction for “inappropriate” attire will be applied for any infraction.
1) Backless leotards: Unless the open area is filled with mesh or flesh-colored fabric, a leotard is considered backless when the open area visually extends:
• lower than 2 inches (approximately) below the bottom of the scapula (shoulder blade)
• wider than the vertical midpoint of the scapula.
2) Racerback leotards (see above backless definition)
3) Leotards with "spaghetti" straps
4) Bare midriffs.
5) T-shirts
6) Boxer shorts
7) Tennis shoes
c. No underwear (including sport bras) should be deliberately exposed.
• A clear bra strap is acceptable.
d. The leg opening on competitive leotards must NOT be cut or rolled above the gymnast's hipbone.
e. Leotard and/or warm-up uniforms should be worn for march-in and award ceremonies.
f. Gymnasts must change clothes in the designated changing area or restroom. They may not appear
in underwear on the competition floor or warm-up area before, during or after the competition.”
