Best shorts ever

These shorts are A-mazing!!! I am petite, 4’11” and these are 6” shirts are the perfect length for my skirts and dresses. They come mid-thigh which is perfect for me. I am so excited about finding these beautiful shorts! Thank you!

Noticeable waist band

It's very soft and comfortable, but the one thing I really don't like about is that the waist band is so noticeable under tighter fitting clothes. I wish it were all flat. Other than that, it gets the job done.

Where have you been all my life? The best cure for thigh chafing and swamp crotch ever. A staple of my summer wardrobe.

A gift

I was Xmas shopping.

Very comfortable

Even in the miserable hot weather we are having, they feel comfortable.

So comfortable.

I never want to run without this! It fits perfectly, looks fine under running shorts, and turns summer running from a very dicey endeavor into a really sweet time.

Complete comfort

I’m so excited to have found UnderSummers products. These are perfect for me as they’ve solved the discomfort I was experiencing with regular briefs. They are functional and pretty. I actually have something lacy to wear as an undergarment.

United States United States


Was very much looking forward to having a great fitting undergarment to wear with dresses. The size I selected based on the size chart ended up being too large. The quality feels the same as what I have purchased at local department stores. I am not impressed.

Sweet Freedom!!

Sweet freedom from thigh rubbing and rashes! No worries on windy days. I love them!! ❤️

Pleasantly surprised

I bought two pairs to try.  I absolutely love these!  They did not roll up my legs or down my belly.  They were very comfortable and I will definitely consider buying more.  I will say that I think they may run a little big.  I am currently a size 14-16 and bought an xl and a lg (since I am working on losing weight). I feel like the large was a better fit.

United States United States

I love them!

My undersummers are perfect and I love them. I need several more pair.

Shortlettes are generously sized  to hug but not squeeze your curves.  They are not compression and do not feel like nylons/hosiery, shapewear, bike shorts, or compression pants.  Shortlettes are simply comfortable.  They are not made to be tight, feel constricting, shape, pinch, or bind.  The longer lengths allows for maximum chafe protection and comfort.

Correct Fit Guidelines:
✔️ Waist should not roll
✔️ Body should glide comfortably against the skin
✔️ Legs should not ride up while walking

Signs of Incorrect Fit:
✖️ Baggy crotch (too big)
✖️ Running at the seams/Wears to fast (too small)
✖️ Slides Down (too small)
✖️ Legs ride up (too small)

Which is the best fit?

CarrieRae's Recommendations:

Under 5'4" - High Thigh, Athletic, or Classic Styles

Plus Size - Fusion, Classic, or Original Lace

Apple Shaped - Fusion, Classic, or Original Lace

* Order the size in-between your waist and hip measurement.  I.e.  Waist 3X + Hip XL = Order 2X

Pear Shaped - Try them all!

Hourglass - Lace or High Thigh

Slender - High Thigh or Athletic

My Shortlettes fall down, why? Are Shortlettes shape wear? Are they compression shorts?
How are Shortlettes different than other slip shorts or bike shorts? How long do Undersummers products last? Can you let your Shortlettes Show?
