I am all new to this. So i could be missing something. We are planning a wedding for May 2011 (ages away still). But we have already started looking for reception venues, told our chapel, spoken about themes/flowers and set an over all budget plus individual ones, the individual budgets take into consideration the dresses for bridesmaids, i didn't have to think twice about who my bridesmaids would be (my sis and 2 best friends), and it didn't cross my mind that my sil would have to be one. She doesn't really talk to me, and even brought a 30 year old guy (she is 18) back to our house at halloween, and done who knows what in my kitchen and bathroom (but i had to wash sweaty fake tan smudges and hand marks off the wall). Tbh we don't ever speak, i am 23 so it isn't even like i am a scary older lady to her, i have invited her shopping a few times in the past and have always been turned down. But dp's mum asked about her being bm, is it something that just goes without saying, are all Fsil's bridesmaids?
