what loafers would best suit my needs?

I’m looking to get my first pair of actually nice loafers. Heard a lot of great things about meermin. I’m attracted to the leather oak antique calf loafers, but a little worried that leather could give off a little too formal of a look as opposed to suede, but I’m just really on the fence. I see myself wearing these a lot during spring/summer season since I live in a pretty hot/humid environment, so something that would pair well with some linen shorts and a polo. I’d like to maybe wear it with pants as well, but again, because I’m in a warmer climate, it’s unlikely since I tend to prefer comfort over everything. Please give me your suggestions if you don’t mind :))))
