New Englander here... Here it would be tacky to ask a friend/relative to serve cake and punch - that's what the caterer is for.
I asked my 3 closest female friends, and my husband asked his 3 closest male friends, to be in the wedding party. 5 of the 6 had SO's, so we asked 4 of them to hold our chuppah (Jewish wedding canopy that the bride and groom stand under during the ceremony), and we asked the fifth to keep an eye on everyone's handbags so that nothing wandered off.
I'd like to think I wasn't bridezilla
