Suits

Linen? I like the look of them & they are definitely more breathable than traditional suits!

You can also find cotton suits in the spring/summer, but it creases easily.

I was looking online for breathable fabrics I found one called fresco fabric ? But I just thought I’d hear my other brides thoughts too! ☺️

As a natural fiber, lightweight wool is incredibly breathable and wears beautifully; but it depends on what kind of temperature/humidity/etc. you can expect for your wedding and how much they will actually be outside. If the wedding will be outside, 98 degrees and 100% humidity, any fabric is going to be hot & uncomfortable (but synthetics, like a suit that's heavily polyester, will be much worse). However, if the only time the men will be outside is moving from cars to air-conditioned buildings, they should be fine for a quick walk and once they are inside they'll be good.

If you're planning a lot of outdoor activities -- ceremony, reception, photos -- at a time of year when it's very hot where you live, I'd skip suits and do cotton dress shirts and khakis, so they aren't miserable.

I agree with linen, and there are a lot of really cute colors too. We're having a fall wedding, but we'll be inside (a butterfly sanctuary/greenhouse) so it's going to be super warm. We are forgoing traditional suits for my groomspeeps, but I'll have a lightweight suit (with jacket), that I can take off. Then the groomspeeps will have matching pants and white shirts with suspenders and bowties.
