Thought this would be perfect for the big niece because her hair looks similar and she has recently been fond of wearing a cardboard crown that she originally used for a presentation at daycare.
When I found out that it also came in black, I wanted to get one for myself too. The largest children's size is 170 cm and I'm only 163 cm tall, but alas, the cutoff for this shirt is 122 cm.
The niece dodged a bullet there. Matching aunt and niece outfits must rank pretty high on the daycare cringe scale.
