How do I buy SOL with USDT?

Could you kindly explain to me the process of purchasing SOL using USDT? I'm quite new to the world of cryptocurrency and finance, and I'm a bit overwhelmed with all the options and steps involved. Could you guide me through the necessary steps, starting from where I should go to make the purchase? Are there any specific exchanges or platforms that you would recommend for this transaction? Also, are there any fees or commissions that I should be aware of? Would it be possible to do this transaction securely and efficiently? Thank you so much for your help!
