The 'Girls' star is keen for her sister Grace, 24, and her partner Jack Antonoff's sibling Rachel to embrace androgynous fashion during their big day.

She said: "Jack and I have talked about it and we've always said that when we get married we want our wedding party to just be our two sisters in tuxedos. Jack has a straight sister, I have a queer sister; they'd be our best men / women and we'll call it a day. That's our dream."

And the 30-year-old actress likes to refer to the 32-year-old musician as her partner and joked it makes her "kind of down with the queer community".

She added: "I use partner because I like it. We're not married, but also, he's not my boyfriend.

"I feel like it's another one where I'm like, I'm kind of down with the queer community. I have my partner! He's my partner!"

Meanwhile, Lena has always been a fan of androgynous fashion herself.

She shared to PrideSource: "It's funny, when we were little girls my dad always wanted to dress us in a super androgynous way. If we were alone with him for the day, it was a plaid shirt, jeans, sneakers; he just thinks androgynous fashion on women is super cool. One of the first presents that he bought each of us: He got me a suit in eighth grade; he got my sister a suit in high school. He would really push the-ladies-in-suits angle. My mom came up in New York in the '80s wearing a power suit, so the idea of suiting as something that kind of already defies gender lines, I already felt like I had an understanding of. This (movie) obviously takes it to a whole new level."
