The Petticoats are just as important as the Pollera. No lady can wear a Pollera without them. There are two or even three of them in a Pollera, the one used directly under the Pollera skirt is called "luxury petticoat" and should have more labors, ornaments and handmade curiosities.

The petticoats are among the oldest legacies left to us by earlier generations of European women who settled on the isthmus. This historic event is important to value its use. Petticoats were modified in the course of time, when the appearance in the commerce of a variety of materials that were made available to consumers was used to exploit the development of them.

The petticoat is composed of: A waistband that is tied to the waist, a skirt of fine cloth, light and smooth or with hems, horizontal ornaments terminated in braids, linen fabric or cotton thread worked with different stitches and techniques, made over white cloth with lace and embroidery with floral and geometric applications that sometimes blends with the designs of the braid and lace worked on canvas.

The fabrics that have been traditionally used for the underskirts are linen cloth followed in preference by the opal.

The Petticoat or underskirt can be three to four yards wide. This depends on the size of the individual. They are always less extensive than the Pollera´s skirt.

The petticoats are decorated with fine cotton yarn or woven braids. These are made with eye-catching labors that are applied to the bottom and top of the cloth worked generally with embroidery or lace.

The petticoats can be worn at the person preference, but always taking in consideration what the tradition has established.

In the petticoats as with the Polleras there is fantasy and spontaneous creativity. Some prefer four panels with lace inserts; others use handkerchiefs with labors. We've seen embroidered handkerchiefs sold by Hindus stores linked together with lace and braids in a petticoat.

The main lace work is placed at the end of the slip and most of the times the end trimming takes the shape of peaks or shells but never straight. It is one of the parts of the petticoat that admits extra luxury. This is where the weavers show off their abilities. We've seen lace measuring up to eight inches in wide; with labors that matches the design of the braid. When the job has these features, we call it "a complete set of laces and braid."

For this type of weave a yarn ball is used, the gauge of it goes according to the thickness you want the job to be, and this can be 40, 80 or 100.
