Feeling like engagement, being very fashionable (8)

I believe the answer is:

uptodate

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

'very fashionable' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'feeling like engagement' is the wordplay.
'feeling like' becomes 'upto' (I can't explain this - if you can you should believe this answer much more).
'engagement' becomes 'date' (synonyms).
'upto'+'date'='UPTODATE'

'being' acts as a link.

Can you help me to learn more?

I've seen this clue in The Irish Independent.
