The patch never completely removed formal wear. You are always left with a corset with that outfit...which is cool if you are into that sort of thing. You need a supported outfit like terran mirror TOS Top or Winter Jacket Cropped for Federation Toons. You can preview the effects of the various outfits in the tailor. You can purchase the winter jacket - cropped red for under 1,000,000 ec in the Exchange. Below is my character "wearing" the Terran Mirror TOS Top a split skirt and a formal chain belt with studded boots. The Terran Mirror TOS top must be purchased with Zen, but it is an account unlock so if you have multiple toons, they can share the uniform. It is, after all what all good captain's women must wear.
