It looks pretty ok, except for one glaring problem.

As Weiss took in her reflection, one problem became glaringly obvious: you could see her underwear under it. Her bra was most obvious, with the tights adding another layer to slightly reduce the visibility of her panties, but it was still an issue that made her heart race. Turning around, she got a good eyeful of her panties through the backside of the costume.

Other than that, it looked pretty good; the tutu sat fairly well on her hips, the ballet slippers were quite comfortable, and the tiara didn't bother her scalp. It was just a shame that it was so thin, and she didn't have the time to return it. A quick tear through of her dresser did not yield any white under garments she could swap out for.

Standing stumped in front of the mirror, Weiss felt an inkling of an idea worm it's way into her brain: what if she just... removed the issue entirely. Her reflection showed her that other than her underwear, nothing else was visible under the costume; not even her belly button. Nobody would know, and nobody would ever suspect that the prim and proper heiress of the Schnee Dust Company was going commando. The very notion of the idea sent a thrill down her spine that she both hated and loved.
