Hi Leticia,
Thank you so much for your 2nd order with us.
The set is meant to be a loose, oversized, satin set.
This isn't meant to be fitted in any way shape or form. We show it on multiple models and on all of them the set is baggy.
The set does not run big. There is a difference between oversized and runs big. Oversized means it is meant to look baggy by design. Runs big means you should size down because the fit of the product runs bigger than the standard fit for your particular size.
As for the quality, I can assure you that it's top notch. Everyone has their own definition of what something is 'worth' but if you purchased it, you certainly believed the price was right.
If it didn't fit you the way you wanted it to, that's okay, but it doesn't change the quality of the product. The price is based on the craftsmanship of the product, not how you wish it fits you.
