Sesshomaru seemed to sense that something was wrong with Kagome after his statement because he took her aside and spoke to her about it afterward.
"Kagome," he began gently "do you not want a wedding? We don't have to have one if you don't want it." At this, Kagome vehemently shook her head and bit her lip trying to think of ways to explain her feelings on the subject.
"I mean I've always thought I'd have a wedding. But I just never did a lot of thinking on it." He still felt uneasy and probed her just a little further.
"What else is bothering you?" Kagome thought about the reason and finally came out with it by pulling Sesshomaru down and whispering in his ear.
"My mother has been saving her wedding kimono for me."
