"Habe für mich einen in der M und L gekauft. Die Gröẞe M sitzt perfekt, fürs „einfache“ Tragen sehr gut. Die Größe L passt besser zum lümmeln auf der Couch. Ansonsten ist die Passform gut, einzig die Ärmel könnten etwas länger sein und @Opposuit macht die Sachen UNBEDINGT Trockner geeignet!"

Onesie gekocht. Maatvoering is

"Onesie gekocht. Maatvoering is echt aan de kleine kant. Ik hoop dat de was er niet voor gaat zorgen dat ie wat krimpt want dan kan hij de vuilnisbak in. Valt me wel behoorlijk tegen. Ik ben zelf 1. 80 en ben voor de M gegaan. Terwijl ik normaliter s of zelfs xs (confectie 44 broek 28”) qua maat heb (mbt de omvang). Houd dus zeker rekening met het kiezen van je maar. Beter te groot dan te klein."
