Briefly describe the narrator's comments about himself with respect to hair,necktie,etc

I think this is in chapter 7. Here is a quote from the book:

The river affords a good opportunity for dress. For once in a way, we men are able to show our taste in colours, and I think we come out very natty, if you ask me. I always like a little red in my things – red and black. You know my hair is a sort of golden brown, rather a pretty shade I’ve been told, and a dark red matches it beautifully; and then I always think a light-blue necktie goes so well with it, and a pair of those Russian-leather shoes and a red silk handkerchief round the waist – a handkerchief looks so much better than a belt.
