These are pettipants purchased online from HELNI in 2024. I wore them layered under dresses. They add volume to dresses and are cute even when peeking out from the hem. The following is quoted from the website: The material feels so good against the skin that you'll think it's cooler to wear them in the sweaty season. Embroidery runs along the knee-length seam, and wide pleats are attached like frills. They not only prevent see-through but also allow you to broaden your styling options by peeking them out from the hem, adding volume to the hem, or adjusting the length of your outfit. They are also recommended as loungewear at home. The waist is elastic, making them easy to wear. They will be shipped compressed, so please be aware of any creases.
