My sister's getting married for the fourth time. She keeps hinting I should throw her a shower — but is that just tacky?

Luna dutifully showed up for weddings one, two, and three, but now Leann is hinting she wants Luna to throw her a big shower, and Luna just isn’t on board. Luna is embarrassed that Leann is asking people to celebrate her again and buy her more gifts, given they’ve done so many times already. She feels like it’s just getting tacky at this point.

So, is Luna right that a fourth shower would be tacky, and if so, how can she talk with Leann about her decision not to spearhead a lavish party for a fourth wedding celebration?

A fourth wedding shower is one (or more) too many

Luna shouldn’t get out the invitations just yet, as experts agree she’s absolutely right to feel uncomfortable hosting a celebration of another wedding.

“A wedding shower is meant to help a couple start their life together, not restock the house after every divorce,” Lisa Mirza Grotts, an etiquette expert widely known as The Golden Rules Gal, told Moneywise. “By marriage number four, you should have enough appliances to open a department store. Celebrate the love, but skip the loot!”

Grotts said three showers were “more than generous,” while four would be “pushing your luck,” and Nick Leighton, co-host of “Were You Raised By Wolves?” agreed that a fourth shower seems to go against the purpose of the event. “The original idea of the shower was to help a first-timer set up a household. So, after that, some guests may assume you’ve already got a toaster or maybe even three,” Leighton told Moneywise.

Jo Hayes, an etiquette expert and founder of EtiquetteExpert.Org, also addressed Luna’s fear that the event would be tacky, telling Moneywise, “I don’t think I’d necessarily describe it as ‘tacky’ … more, just unnecessary … and, perhaps a little bit cringe.”

Hayes also made clear that Luna should not feel guilty about opting out at all because, after all, “You’ve thrown three previously … I’d say that’s more than your sisterly duties done.”

Luna can bow out gracefully

While Luna doesn’t have to, and probably shouldn’t, throw another shower, this doesn’t mean she has to pass judgment on Leann’s marital habits when she declines.
