Wet suit help please

Hello
I need to know some info about buying our kids wet suits.
Daughter is 15 and 5ft 10"
Son is 12 and 5ft 9"
The will be going surfing in April in Cornwall ( couple of lessons)
Daughter wants her own suit as she is in the cadets and will be doing a lot of water sports off the south coast in the summer
So best places to buy? what to look for ? will one suit do both tasks?
Thanks
