*mailmare uniform* should imply *mailmare*

Background Pony #2FF3
Alternate suggestion:  
alias mailmare uniform -> mailpony uniform
 
The uniform itself doesn’t appear to have any gendered attributes (like a skirt), which ironically, would make your proposed implication sometimes invalid (eg. crossdressing - but since it doesn’t make a difference, nobody would use the “mailmare uniform” tag in that way.)
 
Looks like mailmare should imply mailpony and female too.
