FMIL wants tuxes for a non-Black Tie Wedding

Suspenders

We aren't having a black tie wedding but the guys are wearing tuxes.

Its a 4:30 church wedding. The church is very mission inspired, very so cal architecture, open beams etc. My icon picture is actually the sanctuary, I just don't feel like it is a formal wedding warranting tuxes. And yes it SHOULD be a decision between FH and me. But FMIL just gets her hooks in. I can always tell when he has been talking to her because his fuse becomes quite short!

ETA: Thank you ladies for all the feedback.

I would consider our wedding formal but definitely not black tie. When I think of tuxes I think black w/ a vest or cummerbund/prom (like @Elyse said). This is the one we picked out for FH - no vest and pink ties. The GM's will wear the same style but in a light gray. It's still a tux but I think it seems more suit-like.

All the guys (FH, BP and fathers) are going to be in tuxes. To me that's what really seems to make it a wedding.

I guess I wouldn't mind a tux that's more suit-like, or a suit that is tux-like, similar to what JCB or Becky posted. Most weddings I've been to have been very rustic-themed, or a barn/bbq wedding, and tuxes aren't super appropriate in that setting haha!

The only wedding I've been to, where the men didn't wear tuxedos, was a casual one held at a day camp. The men wore vests and ties. Even in outdoor weddings I've attended, the men wear tuxedos. I lost count of the number of weddings I've attended, in the past few years; it was 6 this year and at 4, so far, in 2016. All of them began very late afternoon (4:30 PM) or later, except for Catholic weddings, where the ceremony is in the afternoon and reception at night. 3 in the last 2.5 years were black tie, including my own.

P.S. My Mom knows someone whose brother chose buy 1 get 1 free suits, for his bridal party. The friend said that by the time he had the alterations done, and bought the necessary accessories to go with it, the half-price savings disappeared.

FH and all groomsmen, fathers, ushers, and readers will be wearing tuxes... Ours is not a black-tie wedding, but it is formal (it's going to be in a Catholic Church). This will be the plan, unless something changes (who wears what color vest/tie). They will be in black tuxes.. FH will be in a light ivory vest and bowtie; groomsmen I think will be in a blue vest with a royal blue/black striped tie; fathers in a black vest with royal blue/black striped tie; ushers in a black vest with a royal blue/black paisley tie. As for the pocket squares -- I can't remember if it includes the pocket square or not... we aren't sure if will even use them anyway. As of right now, only FH will be in a bow tie, while all the other men will be in long ties (but that might change).. We are going back next week, while my dad is visiting to revisit what we decided to do.

I've seen a variety of suits vs tuxes in weddings. Most of the semi-formal and formal weddings I've been to, the GM wore tuxes. But, I have seen semi-formal and of course casual weddings, where the GM wore a suit.

Oh.. so I didn't really know what the big difference was between suits/tuxes. But I guess the big difference is satin (tuxes incorporate some use of satin while suits do not).. Here are two photos and then a link for anyone who wants to read up more about it.

My guys wore tuxes

My FMIL is in favor of tuxes as well where I’d prefer suits since I think it’s more cost effective. I’ve seen not black tie weddings with the BP in tuxes and ones where the BP were in suits, both look fantastic and go well even if the guest attire is not super formal
