Mixed gender wedding parties - how’d you style them?

A lot of people do the traditional super matching thing on each side but since you're already breaking from tradition with mixed gender bridal parties, why follow such customs?

You can have all the men (groomsmen and bridesmen) wear the same suit if navy is a wedding colour but also differentiate them by having the groomsmen wear a long tie and the bridesmen wear a bow tie in the rust/orange colour of the bridesmaid dresses. While my samples of a rustic sports coat/blazer could look nice, the benefits of a navy suit are that they are easier to find and much more rewearable for the men for other future events.

For the groomswomen, you can just have them wear the same dress as the bridesmaid instead of navy (so that it's not just all blue up at the altar) but add a small accessory of navy to them, like a sash-type belt or a blue corsage, to differentiate them.

Yes exactly. All boys in black suits and white shirts, with accents of the bridesmaid dress colours (pocket squares on my side, boutonnieres on his)

Are the groomsmen wearing any rust/orange elements on their suits? Like a tie, boutonniere, pocket square etc? If so, just have all the men wear the same thing. Or if you have a secondary colour other than rust/orange (not sure if navy is a wedding colour or just your choice of suit) you can have groomsmen wear that as accessories while the bridesmen wear the rust/orange.

If you really want the bridesmen to look more unified with the rust/orange, you can give the option for autumn-coloured sports coat or blazer. That would look really nice for an autumn winery wedding. A blazer would cost less than a full suit and they can just wear a pair of dress pants they already own. With blazers and sports coats, you get more variety in colours. Examples below (ignore the dress style - they can be formalized with the right accessories). I personally wouldn't worry too much about being 100% match between the bridesmen and bridesmaids. As long as they look cohesive, it'll work.
