Hello and welcome to our community! Is this your first visit?
Where will the trainers take him for his dives as they may have hire suits he could use rather than buying one.
May be worth checking.
the original post was from June 2018 so I would guess that the dives have been done and the teenager grown a little.

Unfortunately, finding good suits for someone with an unusual body shape is difficult, as manufacturers make suits in popular sizes. I faced a similar problem myself when I started wakesurfing. Still, I managed to find a good suit at a reasonable price in an online store. It was really good quality, and I was not cold even when falling in cold water. When I first started surfing, I had a hard time keeping my balance which caused me to spend most of my time in the water.
