"Dummy" newbie seeks advice on swimsuit

Hi all, First post :wine: !!! Looking for some info here, I am looking for a swimsuit. I have to tell you guys I left the pool for the last 20 years. I see that the old speedo has changed a lot in the last ...few years, and wanted to know if there's something that could be better suited to my incredible tendency to sink down the pool... I will be joining the Masters team and swim 3 times/week as cross training for the winter (I ride 5000-7000 mi. cycling in the summer). I'm 5'10" 175 lbs (short legs, lot of weight on the lower part of the body). So , with the lower part of the body tendency to sink, is there an advantage to use a specific type of swimsuit ? I will not spend hundreds of dollars on a swimsuit, the goal is not to save hundredths of a second, but to get something that's used as the norm nowadays. Got brands and models to suggest ? Thanks all, Louis:)
