When it comes to rompers, always choose pure cotton. However, party rompers may look better in silk, lace or polyester, depending on the type. While these blends are fine for short term wearing, the cotton ones work well for all-day and are better to maintain. For evening wear, flowy satin or georgette is an excellent choice. Satin looks luxurious and classy on its own, but you can up the look with accessories. Make sure the fabric is light on your skin and doesn’t cling too much, especially when it gets humid.
