This one from Northanger Abbey:
She went home very happy. The morning had answered all her hopes, and the evening of the following day was now the object of expectation, the future good. What gown and what head-dress she should wear on the occasion became her chief concern. She cannot be justified in it. Dress is at all times a frivolous distinction, and excessive solicitude about it often destroys its own aim. Catherine knew all this very well; her great aunt had read her a lecture on the subject only the Christmas before; and yet she lay awake ten minutes on Wednesday night debating between her spotted and her tamboured muslin, and nothing but the shortness of the time prevented her buying a new one for the evening. This would have been an error in judgment, great though not uncommon, from which one of the other sex rather than her own, a brother rather than a great aunt, might have warned her, for man only can be aware of the insensibility of man towards a new gown. It would be mortifying to the feelings of many ladies, could they be made to understand how little the heart of man is affected by what is costly or new in their attire; how little it is biased by the texture of their muslin, and how unsusceptible of peculiar tenderness towards the spotted, the sprigged, the mull, or the jackonet.
