Why Wear Shortlettes as Pajamas?

Our fabrics are lightweight to keep you dry and cool.

The seamless inner thigh reduces friction points producing a comfortable barrier of protection to combat sticky thighs during the night without riding up or being tight.

No more pinching or riding up in the crotch.

The shortlette feels like you are wearing nothing, while offering modest comfort.

LOVE Long Leg Shortlette 15”

I am so happy with this purchase! I probably ordered the long leg shortlette for a different use than most. I was looking for the perfect sleeping shorts with my T’s. Yep no real PJ’s for me! I wanted something that wouldn’t crawl up during my sleep and these are the perfect weight, length and fabric to give me a comfortable and restful night of sleep! I have been known to just stay in PJ mode all day and I like that these look like shorts and a top! Haha not sure I’m fooling anyone that I didn’t get dressed for the day but I’m so comfortable! I found them true to size and shipping was prompt! I will be ordering more! Thank you undersummers for this great length!

Soft, moisture wicking, amazingly comfortable. The 15” is perfect under a maxi dress, slacks, jeans, and leggings. The hidden pocket in the waist is very convenient for a panty liner or pad when you don’t have pockets.



Thank you for leaving such a great review! We are so happy you love your Undersummers!

Long Slip Shorts | Anti Chafing Underwear

If you wear dresses that don’t have enough coverage to cover your bottom, or if you are concerned about the risk of chafing when wearing shorts under dresses, you can buy Long Slip Shorts. These anti-chafing underwear are designed to protect your thighs from rubbing against each other. They are available in a wide range of styles and materials to suit different body types and clothing styles.
Ultra soft fabric

When looking for a new pair of slip shorts, choose a pair that is made from opaque, soft, and breathable fabric. It should also be stretchy to allow for full movement.

These long slip shorts are a great choice for women who want to feel comfortable and safe while going out in the sun. They are made from polyester and spandex and come in a variety of colors and sizes.

These beautiful lace slip shorts are an excellent choice for tall women who want to avoid thigh chafing while wearing long skirts or dresses. They are comfortable to wear and have no binding seams, so they stay in place while walking or sitting down.

These high-quality slip shorts are designed to keep your thighs protected from friction and chafing while you walk, bike, run, or do yoga.
