Sarah, what is "inappropriate", going in bikinis to a holy place or wearing a prayer item? There's no single prohibition in the Torah concerning women and tzitziyot (let alone the word "tallit" doesn't even appear there!) so there is no whatsoever halachic problem. This is just the latest show-off by the swinish Orthodox estabilishment of Israel!
