Well, Islam never specified what clothes to wear, it just set requirements.
Muslim women need to cover everything except the face and hands, so I'm afraid to tell you that the clothing you're asking about is not 100% correct, and I wouldn't wear it, but it's up to you and your relationship with God what you want to do.
The fact that you live in a very hot and humid area only gives you more ajir if you dress properly. God knows how you feel and because of that (like I said) will reward you more.
Good luck, and if you need anymore help contact me: email@example.com
