Chihaya is no fashion queen herself. If you remember, her was quite excited with Shinobu's shirts. In fact her fashion sense is probably worse.
The only reason she dressed well was because all her cloth are either hand-me-downs from her model sister or they are picked out by her. The manga mentioned that both in normal chapters and omeke.
Besides, that is all part of Shinobu's allure and moe points.
