Reina clothes are usually made with elastic fabrics, which are best looked after if you hand wash them in cool water and hang them to dry with care on a line, preferably without clothes pins. You may apply medium temperature ironing after they dry.

Regarding the dresses which are made with stretch velvet and decorated with rhinestones they need to be carefully wringed after cool water hand washing so the stones remain intact. Same tips for hanging to dry, clothes pins and ironing apply as above.
