I decided I needed another red pants fic. Also this is loosely based on this artwork by Cylin:

Incomplete Data (or The Effect of Red Pants on One Sherlock Holmes) – Sherlock is quite surprised to realize what red pants do to him.

“John have you seen my…” Sherlock stopped in the bathroom doorway and froze.

“What did you need, Sherlock?” John asked mildly. Sherlock stared, as though truly noticing for the first time the strong lines of his body. Firm arms and legs, broad chest. And all those lines led to a magnificent pair of red pants. He was bent over, tugging off his socks with the shower on behind him.

Several things crossed Sherlock’s mind in that moment, none of them relevant to his original intent. “Those pants suit you very well,” he said instead.

A smile bloomed on John’s face. He put his hands on his hips, which Sherlock found did even more things to him. “This requires more data,” he muttered.

John watched him as he pulled off his dog tags and set them next to the sink. “What sort of data?” He hooked his fingers in the band of his pants. Sherlock’s mouth went dry.
