Do not take legal advice from posters on an internet forum; that especially goes for advice from people who are not in your country and/or who are not professionals.
When I started out, I took some pictures of just the belly of a pregnant woman and was told by my agency that I would need a release (which I had) in order to ensure that the images could be sold globally. Their lawyer's assertion was that the shape of the belly would be considered an identifiable characteristic in some countries.
In the UK and probably other places the law states that you can shoot anything and anyone you like a public place for personal and commercial purposes without the need for any permission to be granted, providing you do not hinder them, cause obstruction to vehicles or fall foul of the anti-terrorism laws. Despite what some Police and media brainwashed parents seem to think, there are no laws against taking pictures of children in public but you spend ages with a huge tele shooting someone's kids on a beach you might well be accosted by nervous parents or local Police. The reason people fall foul of some laws is places like local council run gyms, swimming pools and shopping malls/centres, they are almost always private property and do have their own rules on photos usually at the discretion of the manager in charge.
The laws are wonderfully ambiguous, mainly to keep solicitors and lawyers in well paid jobs! "Reasonable expectation of privacy." is the classic one, so no shooting from the public road with a huge telephoto into someone's bathroom!
If it is like it is here in the US, you don't need permission to sell the photos. As long as they're being sold under the context of an art print, you're ok. What you can't do is sell the commercial rights or use them for commercial purposes without signed consent. Basically, as long as you're not using the photos to endorse a person, product or service (including your own photography services) it's ok.
