The simplest skirt from the main market can look as good as a product of an expensive brand for thousands of dollars. The point is a few stitches. If the item does not sit perfectly straight from the hanger, then take it to the workshop without even bringing it home. The result will be worth the extra cost.
And while choosing outfits, remember that the easier the cut, the easier (and cheaper) it is to correct it for a perfect fit at the tailor.
