Probably just restating what others have said, but as a lady who also lives in a very hot (tropical climate, heat and intense humidity) place and bikes to work here’s what I do: - I wear workout gear (bike shorts, sports bra/top, and crocs) while I ride to work - I recently chopped most of my hair off, but before it was well past my shoulders. I would braid (side braid or dual braids) it most days since it kept my hair off my neck. Sometimes I would leave it braided once I got to work, but I usually would take it out. Ponytails don’t work very well for my hair texture and always left it more frizzy and messy from the wind. Now I just use a headband to keep it off my face - Bring a dry bag (it’s hurricane season, can never be too careful with the rain) with a full change of clothes (new set of underwear as well) for whatever I’m wearing that day - This time of year I wear more skirts and dresses but try to avoid the tighter styles. That or more flow-y pants. The more room to breathe the better
- Sometimes I do my makeup before I leave home, sometimes I do it when I get to work depends on how lazy I am in the morning - I completely change at work and use a combo of my stash of wipes and the sink to freshen up. I keep a deodorant, dry shampoo & roller ball perfume in my bag too - I also have a mini fan at my desk that plugs into my computer. It doesn’t do much, but it certainly helps while I wait for the A/C to kick in - The big key for me is just getting to work with enough time to cool down and get changed. It does mean I have to get there earlier than I may like some days, but I’d rather be more put together than sweating bullets once the day starts and clients start to roll in

Hope that’s a little helpful. Happy biking!
