I believe the answer is:

singlets

I'm a little stuck... Click here to teach me more about this clue!

'tops' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps there's a link between them I don't understand?

'just one t-shirt for starters' is the wordplay.
'just one' becomes 'single' (similar in meaning. I am not sure about the 'just' bit.).
'for starters' suggests taking the first letters.
The initial letter of 'shirt' is 's'.
'single'+'t'+'s'='SINGLETS'

'and' is the link.

Can you help me to learn more?

(Another definition for singlets that I've seen is " Garments".)

I've seen this clue in The Guardian and The Telegraph.
