Ruby Hoshino's Oshi No Ko costume centers on a red puff sleeve dress with a black ruffle hem. Ruby is Ai Hoshino's daughter and Aqua's twin sister, a bright, stubborn idol in the new B-Komachi who pursues the stage her mother once stood on.
The Ruby Full Set, Piece by Piece
The Ruby Full Set contains the dress, waist belt, choker and hair ribbon. The stated material is polyester uniform fabric. For this set, the selectable size labels are S, M, L, XL and XXL. A wig, star contact lenses, socks and shoes are excluded. Build any additions around the supplied dress and accessories: a blonde wig can follow Ruby's hairstyle, while your choice of socks and shoes can be part of your own styling. The hair ribbon is already included, so account for it when planning the hairstyle.
Red Puff Sleeves and a Black Ruffle
The dress's red colour and black ruffle hem give you two specific details to feature in photographs. Try a wider composition that includes the hem as well as the puff sleeves when you want to show the dress as a whole. A closer portrait could instead focus on the sleeves and choker. For a small photo series, alternate those views so the dress and its accessories each receive attention. For a dress detail, try a separate crop showing the point where the red dress meets the black ruffle hem.
Blonde Hair, Side Tuft and Ribbon
Ruby wears long blonde hair with a side tuft. For that hairstyle, use a blonde wig and consider how you want to position the included hair ribbon. You might choose a portrait angle that gives both the tuft and ribbon a place in the frame, then take a separate image with more of the red puff sleeves visible. Star-pupil contacts are another optional addition for Ruby styling. They give you an eye detail to consider alongside the wig when planning a closer character portrait.
The Ruby Set From Different Angles
The costume gallery supplies a front image, a side image, a back-angle image and an image of the full set pieces. Use the pieces image to review the dress, belt, choker and ribbon together. The other images offer references for viewing the same Ruby Full Set from different directions. If you want to mirror that approach in your own photographs, plan a front pose, a sideways pose and a back-angle pose. For the back-angle photograph, you could turn your head slightly to work the hair ribbon into the composition too.
Ruby Beside Aqua or Kana Arima
For a sibling photograph, pair Ruby with an Aqua cosplayer. A Kana Arima cosplayer is the suggested partner for a B-Komachi shot. Each pairing draws on a different part of Ruby's character background: her twin relationship with Aqua or her place in the idol group. If both partners are taking part, you could arrange separate Ruby-and-Aqua and Ruby-and-Kana portraits, followed by a shared frame. Try placing Ruby in the centre for that image, with the red dress and black ruffle hem visible. For a closer group portrait, you could arrange your poses so Ruby's red puff sleeves remain visible beside Aqua or Kana. Keep a solo Ruby portrait in the sequence too, so the dress, waist belt, choker and hair ribbon have their own photograph alongside the character pairings.
