If you’re inviting George Kotsiopoulos over for a party, take note.

“I’m the guy who will dim lights or unscrew bulbs at your party if the lighting is not flattering, or plug in a playlist from my phone if the music is not creating the best mood,” the former Fashion Police co-host tells PEOPLE. “Horrible ambience is a no-no at any age.”

Another holiday party faux pas that Kotsiopoulos, 48, says is a definite ‘don’t’ for hosting guests: “Not having enough food, booze and ice is inexcusable for any host over age 30,” he says. “Do not invite people to your home if you are unable to provide these things. If you cannot, then it’s totally fine to make it a potluck and/or BYOB.”

Everything But the House

Kotsiopoulos is a seasoned pro at throwing a swanky soiree like the one he put together with online estate sale marketplace, Everything But the House (EBTH). His hard and fast rules for a memorable gathering include his mantra, “more is more, so laugh louder, dance faster and eat whatever you want, just don’t get crazy,” as well as one other tip that can sometimes get lost in the shuffle of entertaining to-dos.

“A good host is literally the life of the party,” he says. “If you’re not having a blast, then your guests probably aren’t either.”

Simple steps like introducing guests to one another, planning for enough food and drink — “My Greek parents taught us that guests come first so it would be an embarrassment to run out of food or libations,” he says — and putting together an activity to break the ice are a few ways to keep the celebratory spirit alive.

“For the holiday party I’m hosting with EBTH, we’re doing a White Elephant gift exchange of unique items I’ve been curating and coveting,” he says. “Since I want to steal every single gift, I’m hoping everyone else does too!”

If you’re the partygoer instead of the party thrower, Kotsiopoulos also suggests giving the host or hostess a gift.

“It’s about being a gracious guest, which is always in fashion,” he says. “Make sure you either attach a card or personally hand the gift to your host. After all, this isn’t an anonymous charitable donation. It’s a gift and we want credit for bringing it. Am I wrong?!”

An attendee at one of Kotsiopoulos’s shindigs is welcome to bring a last-minute guest if the event isn’t seated, but keep these final parting words in mind.

“I trust my friends to bring what I call ‘good party guests,’ so I don’t mind a surprise plus one,” he says. “But if you bring a Debbie Downer to my party, then don’t be surprised if you’re not invited again.”
