Tolles Kostüm

"Mein Sohn wollte unbedingt als Super Mario zum Karneval gehen. Hatte dieses Kostüm dann gefunden und bestellt. Ich hatte die Hoffnung, dass es kein billiger Stoff ist. Und ich wurde nicht enttäuscht. Super bequem und fühlt sich gut an. Größengetreu"

I had to guess size,

"I had to guess size, not having shopped with you before, but a 10 - 12 fitted beautifully on my 10 year old. He was delighted with it. It appears well made too. So I am a happy granny."
