I am getting married in October 2021 and was planning to wait a bit before asking anyone to be my bridesmaids. FH is still selecting his groomsmen and will likely have fewer than my bridesmaids selections. I was going to make my final choices and match up our numbers once I know how many groomsmen he will have. My sister will definitely be my MOH, but I haven't asked her yet. My parents have been pressuring me to ask her because she has been asking them if she will be MOH. I really wanted to ask her at the same time as the other bridesmaids and do it in a cute way. I thought I had some time because my wedding is in 2021. Is it okay to wait and ask her with the rest of the bridesmaids?
My mom thinks I am waiting too long to ask my MOH because I already have a venue chosen and my wedding dress (I took my mom with me to get dress ideas and ended up loving one - ideally I would have brought my mom, MOH, future sister-in-law, and future mother-in law). I don't think this is too big of a problem as the dress was getting discontinued, was on Black Friday sale only that day, and my idea is to bring everyone to a fitting to find a veil/headpiece and to try on dresses for the bridesmaids and my mom and future mother-in-law.
