Hello! I am fairly new to lolita and I've recently come across a couple of offbrand blouses that I would love to incorporate into my wardrobe. The only problem is, they are made of a shiny polyester fabric, giving them sort of a satiny look. I was wondering if that was a definite no-no, if there are some do's and don'ts or if there was no problem to it? They definitely don't look 'costume-y', they are store-bought blouses with a shiny edge. Thank you!
