Fashionable daughter, excited primarily leaving for Texas mission (5)

I believe the answer is:

alamo

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

'texas mission' is the definition.
(the Alamo Mission, fortress in Texas)

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for alamo that I've seen before include "The answer is a place of siege" , "Historic Texas mission station" , "historical Franciscan mission" , "Mission building in Texas, site of famous siege by Mexico" , "US mission" .)

I've seen this clue in The Independent.
