Need Suggestions for Bridal Shopping

Hi. I will be getting engaged in a few months and I am quite anxious about my bridal shopping. I don't know where to start from. Can someone suggest good shops in Bangalore where I can get lehengas and suits for a decent price. I come from a humble background and don't want to waste any amount over things that won't be worn later. For jewellery, I have bought some daily wear pieces in pure gold but they aren't exactly wedding material. Is it okay to wear imitation or fashion jewellery on your big day ? If yes, where do I buy some good pieces from that compliment my outfits. I am a north indian who is currently residing in Bangalore so please suggest shops accordingly. Thank you so much.
