Puh! That costume is just wrong on so many levels. First Starfleet uniforms have solid colour schemes not ones with patterns like in her shirt. Two, she is obviously wearing a skirt and per Star Fleet regulations 1108B that is not permitted any longer. There where too many reports of people walking into the warp core while being distracted as ladies walked above them on the glass floors common to most engineering decks. And three. THE DAM COMBADGE IS ON THE WRONG SIDE! Unless of course she is from the Mirror Universe in which case it is acceptable. Lastly you can clearly see the outline of a nipple on her right breast and there for she is not wearing a Starfleet standard bra!
