So, the sentence would be: "Father chose only a wardrobe of trip."
However, "wardrobe" might not be the most fitting word in this context, as it typically refers to a collection of clothes owned by one person.
Here are some alternative options, depending on the specific meaning:
* "Outfit": "Father chose only an outfit for the trip." (If he chose one complete set of clothes)
* "Few items": "Father chose only a few items of clothing for the trip." (If he packed very lightly)
* "Selection": "Father chose only a selection of clothes for the trip." (If he carefully curated his clothing choices)
Ultimately, the best word depends on the context and what you want to emphasize.
