The first 4 looks are great! Jacquard and sequins done right!
Then it started to be messy, a bit repetitive (he is doing those same architectural silhouettes everytime) with some glorious moments here and there.
I think Halpern is great as "a moment": one dress in the RC, one dress at a party...etc.
As a collection, it doesn't work because of the limited setting around the whole thing. His draping is not even exceptional.
It's fine and forgettable.
