160の相方に着せましたが何とか着れました。 他の方も書かれてましたが、脇の下が結構開くので横乳が出そうになります。 思ったより伸びる生地でしたが、160くらいの人ならBIGサイズをおススメします。

152センチ・47キロの女子です☆ 旦那さんの誕生日のサプライズでMサイズを購入しました* まず触り心地がとっても良かった!ツルツルスベスベで◎ そして着心地も◎!普段家で部屋着にして着たいくらい気持ちよくて伸縮性もバッチリ! 猛暑になったらこれ着てたい(笑) 伸縮性がほんとバッチリだから、あんなこととかこんなこととかすんなりできちゃうな~~と妄想しちゃいました/// ちょっと残念だったのが、脇下が結構下にあるので胸がはみでちゃうこと…家で着る分には問題ないけど胸がおさまらずに乳首まではみ出しちゃいそうになるのが恥ずかしくて;; そういうプレイと思えば楽しいですけどね☆ ちなみに旦那さんは「ここで手を出したら負けな気がする…」と言って、結局なにも起こりませんでしたぁ!・笑

しっかりしていて、実用的にもつかえるんじゃあないですか。 室内で着用させて、バスルームでシャワーを浴びさせました。 かわいい感じで、いいと思いましたよ。 普通に使っているスクール水着と、遜色ないように思います。 大きさも、十分で、何も文句はありません。

本物の水着よりは薄く柔らかいです。 ガタイがいいので肩紐の脇の位置が胸までかかってきてしまいました。 ネットにいれて洗濯していますが、毛羽立ち、毛玉などでなく、扱い安くはあるとおもいます。
のび~る! BIGサイズを購入

思っていた以上にのびます 生地自体は薄めですが透ける感じではないです すごく伸びるので着やすいのですが ちょっと大きいのか脇下が結構下になり、女装の為シリコンブラ等を着けると シリコンパッドが横から見えちゃいます 自分にはちょっと大きかったのかもしれませんね(私は身長168cmです) 色々工夫して無理だったらMサイズ買おうかなとおもいます 色やデザインはとても気に入っております コスプレの旧スクって、明るめの色で全然旧スクって感じがしないのが多いですが これは見た目は本物に見えます

こちらは伸びると書かれていたので、期待しておりましたが、レビュー通り伸びて着やすい感じでした。 ただMサイズにしてはやや大きめ? 伸びない方のMとはかなりサイズが違う?と思ってしまうぐらい違うと思います。 この伸びる生地を使うのであれば、Sサイズがあっても良い様に思います。 白ラインは無い方が好みでしたので、次回の生産の時にはオーソドックスな単色で出してくれると嬉しいです。

旧スクにこだわりがありレビューを参考に購入しましたが、ほぼ満足です。 ただ、彼女が小柄なのでSサイズがあれば完璧でした。 水抜きもあり、こだわられる方でも充分満足できるはずです。

Mサイズを購入した 伸縮性がかなりあり2Lサイズ位まであります。 ピッタリ感あり…キツさは無いです 但し…縫製の限界は有り
