How do I say "I need some advice about X"? For example if I'm going to a wedding in a few weeks, I might ask my friends "I need some wedding clothing advice" or "I need some advice about what to wear".

I know that I can directly ask 参加婚礼穿什么好？or something along those lines, but is there an indirect way to introduce the question? Like the English sentences I wrote above. How could they be naturally translated?
In Chinese, what we would naturally say is


  你知道参加婚礼应该穿什么好吗？


Or even more indirectly


  你觉得参加婚礼应该穿什么好？
