Street Attire is 6 pieces, in fact it uniquely comes in a coffer when other Mogstation items come as individual pieces, because they can't fit 6 items in a single message, but they can fit one item that splits into 6 on use.
Please understand and look forward to it, small indie dev company with limited resources.
From my point of view, the Educand's Attire designs were heavily inspired by the traditional Japanese school uniforms, both male and female uniforms. Traditionally, it's the male uniform that comes with hat, while the female uniform comes with sailor style neck and tie, thus, when adopted into the Mog Station, the female/skirt version doesn't have the hat like the male/slacks version.
That's a shame, I really love the armband version of the sailor uniform. In my opinion, 18usd for the in game costume set is quite a bit too much for my liking. While I do like the style of the skirt one for the sailor uniform, I think I might grab it during the sale.
Isn't there a separate team in charge of mogstation-exclusive item creation?
In that case, it feels like that team should get their shit together. I don't necessarily mind continuing to not buy mogstation items, but it is pretty silly to watch them try to wring money out of people with cut corners, such as the entire fiasco with the Gaia attire (no hairstyle, one-piece outfit) and now this, with one set having one less item and the other set having a headpiece but Hrothgar and Viera still can't use it.
The female set also dyes terribly.
But none of the stockings in this game come by themselves. They're always attached to a skirt, shorts or underwear. When they're not attached to the feet slot. I do wish we could just get just leggings/stockings by themselves. Along with shoes that didn't come with the feet portion of the socks/stockings.
