This isn’t a costume, but the new clothes this dad bought for his daughter. Shopping for clothes for young children shouldn’t be that much of a challenge – more often than not, they don’t really care what they wear, as long as it’s comfortable and they can run around in it. This ensemble certainly looks comfortable, that much we can say.
We don’t want to sound outdated or anything, but perhaps her mother should’ve gone shopping instead of sending her father for this task. Men can hardly shop for themselves, so expecting them to guess what their kids would like seems like too much to ask.
