Fine but not great
It fit well and looked ok. However the material was thinner and flimsier than I expected. It was quite wrinkled and I couldn’t iron it well without risking melting it due to the polyester content. After ironing for about an hour on low heat it was passable but it was a lot of work to only get a passable result.

Q enviaron un producto usado
Size: 7, Color: Black, Size: 7, Color: Black
El traje me gusto lo pedí en size 8 y le quedó grande a mi hijo, lo volví a pedir en un size 7 y lo q me entregaron fue una mercansia usada llena de brillo y mal olor, desde q abrí el paquete se veía q esta usada, me parece de muy mal profesionalismo ya q deberían revisar las cosas de devuelven para q después clientes como yo no tengamos q pasar por esto
