Lance Bass and Michael Turchin are gearing up for their wedding.
After celebrating their "first anniversary of the first proposal," the twosome is hard at work planning their dream ceremony.
And although they both admit planning is "happening very quickly," the couple already has a vision for one important element: their fashion.
"We love fashion, but we also like to be comfortable," Bass told E! News exclusively at 6th Annual Club TACORI Event in Los Angeles. "We love anything tailored...When it's tailored you better feel skinnier and sexier."
It also helps that they can actually fit into each other's clothes as they design their own tuxedos. Just because they wear the same size, however, doesn't mean they want to look exactly alike.
"We're definitely not going to be twins," Turchin shared. Bass added, "Yeah, the whole twins thing went out in the '90s, when 'N Sync dressed like each other."

Speaking of the boy band, when asked if Justin Timberlake, J.C. Chasez, Joey Fatone and Chris Kirkpatrick would be in attendance on the big day, Bass said, "Well if you count if the 'N Sync guys will be there, then YES, they will be there."
He also teased "tons of amazing, secret performances," will happen at the ceremony.
Recently, Bass joked to ABC News that the guys "better be there, if not I'll kick their ass."

While the boy band members can count on an invite, the couple now faces a challenge of cutting down their guest list. After their initial plans had about 600 people, Bass and Turchin discovered they have to get it down to 300 people, fast.
"It's so hard, we're still getting it down," Bass told E! News. "I've already had people emailing me really upset that they didn't get an invite, and no one has gotten an invite yet. There's going to be a lot of drama with this list, that's for sure."
Although some pre-wedding complications could arise, the engaged couple can't wait for their big day, which is expected to be televised on E! in early 2015.
"I knew he was the one, because my friends adored him more than me," Bass admitted. "They literally like him more than me. If they were in, I knew something was special about them."
