First time I've bought a swimsuit in probably 15 years and my old Speedo is still intact.  This suit looks great and stays put in the water and with dives. I'd have to say the sizing has changed because my old suit is a 36 and now I have to buy 38's for the same fit.  I went to a store and confirmed this for a variety of Speedo styles.  So I think they're all smaller than years past.  However, having said that, it fits true to size if you know your Speedo size, in my case a 38.
