In an unannounced change, Blademaster's Crimson Stones and other Blademaster's Stones transmogs available from the Trading Post now come with matching chests wrap for female characters, giving them a nicer default look at the cost of less customization.
Note that these wraps are not present on male characters, who remain completely bare-chested.
Taking up the chest slot, these transmogs are perfect for the shirtless and unarmored Monk or Blademaster fantasy, but were flawed in that female characters find themselves showing the default bra for their race, which may or may not happen to match, leaving it up to users to come up with creative solutions.
Previously, female characters were left with their bra showing, unless they used a shirt or tabard to cover it.
Whether or not this is a good change is largely a matter of some debate, as similar looks were achievable by using transmogs in the shirt slot, though that option is now removed — instead, shirts now fit underneath the default chest wrap, resulting in some very odd combinations.
The Wound Dressing previously allowed for a similar look, but now leaves less room for customization.
