So the possessive always agrees with the nominative case of the noun?
The possessive just has to agree with the case. Here it's just a phrase, so it's Nominative.
If it was Genitive, for example, that would be "moich ubrań".
How do you define a singular 'clothes'?
The word "ubranie" basically means one set of clothes. For example the clothes I am wearing at the moment, the clothes I put on my chair to wear tomorrow, some elegant clothes to wear on special occasions, etc.
So it's like an outfit. Ok thanks.
