I have purchased the long sleeved versions in the past for myself - and my youngest is 16.  These are nice just for hiding the tummy on a 'fat day' and the long sleeved ones are a good weight for chilly days that you know are going to warm up.  I bought this specific set for my daughter who had her baby last week, along with a 3 pack of nursing camis to go under them.  She likes them a lot and feels she can wear them beyond breast feeding.
