Casual Official

Cumi, wearing a custom Official ONY-Xean Suit with T.H.E.G. and a dark, sheer top. It doubles as armor,  as it's made from the same materials as her usual costume, which is lined with Chain Mail. The sleeves are actually short, stopping at the elbows, and her feet are in-step styled, but are full Thighhighs and not two-pieced. The top is only sheer below the breasts, and solid reinforced armor around the breasts and above, even around the back.

I like the design, as I thought it would be protective and comfy to wear, even though Cumi is bottomless. The color is based on the ONYX Corporation nestled in the center of Terrakuphais. Their company has massive battleships, space colonies and a robot facility which works with Professor Xan-Ti. They're the ones who own all the Letheta Units and all of the Military variants of the Robot Girls.

She forgot to wear panties, but she'll be fine. She's working in an office, so it's comfortable, apart from the AC and draftiness of standing in front of an open fridge every now and then.
