Main Character Energy

"Bought this for my best friend’s son’s birthday party. He loved it. It’s very high quality and he immediately recognized the brand “opposuits” because I gave him a full SpongeBob suit for his birthday last year. I hear he wore it to a wedding and it was a hit there, too. This is the good stuff. I like this brand a lot!"

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"
