Out of the 8 people that attended our wedding, we only still see the ones we're related to... our 2 mothers + BIL (and he's on a thin rope lol). The +1s fell off due to break-ups, and the other two turned out to be constant drama whores so we just drifted away some years later.
I'm in contact with all but 1 of 7; I'm related to 5 of the women I had in my party. If I could do it over I would only ask 3 - my sisters and my SIL - not because I am not still close with the others, just because 7 feels excessive looking back.
Eta- if I was getting married to someone else entirely, I'd have no bridal party at all.
All, on both sides. Very small wedding, so my sister was my only attendant, my younger BIL was H's only attendant, and older BIL was our officiant.
And if we were to get married today, the 20 people who attended last time would still be invited. I don't like the husbands of two of my closest friends (both have cheated and are also fairly obnoxious in general, both friends have decided to stay married. I tolerate the husbands but don't like them) but they would still be invited...
