Tips on finding suits.

I've been looking for suits for some time. I'm getting married outside, in the shady luckily, in Florida in August. I've been looking for light fabric that won't make a bunch of my groomsmen sweat profusely. Everywhere I look I can't really find the color pallet I'm looking for. So I've come to reddit so see where you found your suits, and/if they help customize.

Really looking for links, and information. My trying to avoid Grey or Black suits. Thanks for any information.

Also been looking at groomsmen options. I was thinking of providing two different options find a suit that can also be rented and purchased. Give them the option to buy and get tailored or rent and have what they have.

Was thinking of just getting them Vest and Ties as part of their groomsmen gifts and then letting them buy/tailor a shirt/pants and have them have the option to wear or not wear a jacket due to the heat.
