NCAAW question
 

Is it a T in NCAAW rules to wear an illegal undershirt?

No. Here's the A.R.:

A.R. 9. May a player remain in the game when she is wearing an illegal
undershirt or undergarment?
RULING: No. Similar to the rule regarding jewelry, illegal
undershirts or undergarments shall not be worn. A long-sleeved
undershirt that is not a compression/tight fitting shirt is considered
to be an illegal undershirt. The player shall leave the game and
remove the illegal apparel; however, no technical foul shall be
assessed.
(Rule 1-23.1 and .2)

That's what I thought. Thanks for the reference.

On that note, what is the undershirt rule in NCAAM? I saw highlights from a local D1 game the other day. The visitors had maroon jerseys on. There were at least three different undershirt colors among the team...maroon, black, and white. Is it just not enforced at the D1 level or is the rule different than NFHS?

Section 23. Undergarments
Art. 1. An undershirt is considered to be part of the game jersey and must
be a color similar to that of the game jersey as defined by the neutral zone.
In addition, the sleeves and neckline of undershirts shall be unaltered
(e.g., no cutoff sleeves or cut necklines). Both sleeves shall be of the same
length and not extend beyond the elbows. No logos, decorations, trim,
commemorative patches, lettering or numbering may be used on an
undershirt. The same color must be worn by teammates.
