Blouse and panties.

After a brief deliberation, Ruby had decided on what she would offer Weiss to wear. As much as Ruby wanted to help Weiss the best way she could, it still meant that she would be partially exposed as well, which is something that would bring her great embarrassment as well. The best she could come up with would be to give Weiss her top as well as her panties, as this provided optimal cover to Weiss whilst also minimizing Ruby's own nudity. Her cloak served well as cover for her upper half so long as she kept it tied properly, meaning her only bra-clad top was protected. As for below, her leggings would blend with the same shade of black beneath her skirt, hopefully providing the illusion that she wasn't going commando.

Taking a deep breath, Ruby undressed herself and handed the clothing around the tree to Weiss. "Here you go."

"Thank you Ruby!" Weiss once again exclaimed in joy. "I understand how big of a favor this is, but I am so grateful for your help."

"Yeah, no problem." Ruby replied, already experiencing the embarrassment from being exposed, despite no one else being around. The faint breeze had started to tickle her upper-body, making her pull her cloak around tighter while also pressing down on her skirt as her butt and vulva began to feel the chill.

As for Weiss, she had finished sorting out her borrowed top which was only a touch tighter than her own blouse, and now held up the panties that Ruby had leant her. Despite being light-pink with cookies printed on them, Weiss didn't find the garment to be childish, funny, or otherwise embarrassing to be worn in the slightest. With how dire her need for cover was, they were practically made of gold in her eyes. Bending over, she stepped into the leg-holes and pulled them up to finally protect her genitals from view. The heiress shuddered momentarily as she felt the warmth that still clung to the cloth from when Ruby was wearing them, which felt somewhat perverse after giving it a moment of thought.

_'Is this like an indirect kiss, but with our...?' _Giving herself a quick smack on the face, Weiss banished the naughty thoughts from her mind before they took hold.

"You know, it's a good thing I didn't let my sister convince me to borrow her lucky panties for initiation." Ruby remarked absently, trying to fill the awkward silence with a conversation.

"Why's that?" Weiss humored the girl as she finished checking herself over.

"Because they are less underwear and more a collection of strings."

The heiress was unbelievably thankful for that. She very much preferred Ruby's current panties to being offered a thong.

"Well, now that this bit of awkwardness is finished, let's continue with our initiation." the white-haired girl spoke as she stepped out from cover to join Ruby.
