These are super comfortable. They're cool, and they do wick well so things don't get too humid, which is really nice. I also appreciate that the seams are not anywhere I sit, or that would rub; it's really clever, and it makes these great for when I'm out and about on my bike.


How do Shortlettes work?

Our fabric wicks away moisture & is lightweight to keep you dry and cool.

The seamless inner thigh reduces friction points & eliminates holes between the thighs producing a comfortable barrier of protection.

Our thoughful designs stay put while walking and don't roll down all without squeezing or uncomfortable silicone strips adding to their exceptional comfort.

I recommend this product


I bought 4 of the maternity undersummers and they are a game changer! I love they aren’t shape wear, so they are so comfy and cool for the summer. I now do laundry based on wanting to to wear these everyday.

Not only for pregnancy

So these are the perfect thing for those of who may not be expecting but simply built with some extra in front. They're non-binding and they stay up instead of rolling down. Plus my favorite thing about Undersummers: dresses and skirts just slide over them instead of catching on the fabric and bunching up. Ideal length too! Now for just a few more colors...

Just as Comfy!

These are just as comfy as the original Undersummers!

LOVEEE these shorts so much. I'm a wedding photographer and love to wear dresses to weddings but can't HANDLE my legs rubbing together. These shorts save my life every single Saturday. Now that I'm pregnant, I'm so glad I was able to continue shopping with Undersummers to find the perfect pair or shorts to help me even still!

How to Stay Comfortable During Pregnancy

Pregnancy is the time when your body undergoes so many changes. Your belly gets swollen, you pee more, and you have to deal with discharge from time to time. All of that muckiness can really cause some discomfort, especially when you’re wearing a bra, socks, or shoes that aren’t the most comfortable.
Thigh Chafing

Your thighs are the most likely area of your body to get chafed when you’re wearing tight clothing or shoes. This can be caused by a number of things, including poor fitting clothes and wet or sweaty clothing that rubs your skin.
Slip Shorts

A pair of slip shorts during maternity can be a great way to feel comfortable and stay cool as your baby bump grows. These shorts are made from a stretchy spandex blend that fits snugly over your bump, so you don’t have to worry about them digging in or losing their shape.
Maternity Under Dress Shorts

Maternity under dress shorts are great because they can be worn during a casual lunch with friends or a date night. These shorts come in a variety of styles, so you can find a pair that’s flattering and stylish while giving you the support your growing body needs.

These shorts are also a great option if you want to wear swim shorts during your pregnancy. These shorts are a nice blend of 96% polyester and 4% spandex that’s easy to wash, quick-drying, and incredibly comfortable. They’re available in a number of colors, and go up to a size 4X.
