Costume sizes are always such a thing, most things fall much less than it promises the size. This is not the case! The size L fits with my 40-42 (relatively narrow waist, but a lot of hip) without any problems. And what with me always been an issue: At a height of 1,78m most costumes are too short. This dress is at least long enough that you can not immediately see the Po (unless you bound now ballet moderately through the area;)). Although I will still undergo a shorts, but more out of habit.
If I had some exposure to the costume, it would be the exorbitant décolleté. Even with a C-cup I fill the beiweitem from as yet. But also is not dramatic, with one or two stitches can be the safe Sew from the inside a little, without prejudice to the springs.
Conclusion: This costume is a real looker and suitable for large ladies who are not quite slender. I would definitely order it again :)
