My blue pair was perfect. I loved it, however the poppy colored pair was to small. In fact it was a size small and I wear size XL. I mailed the small back today unopened.

All are made from lovely

All are made from lovely fabrics and are a quality item. My only issue is with the fit, hence the 3-star rating, otherwise this would be 5-stars across the board. The shortlettes with a wide band of lace at the top were too large, despite emailing my measurements through and getting confirmation that L was the right size. I felt they were slipping the entire day, making for a bit of an uncomfortable wearing experience. They also sat lower on the body making me feel I had to hitch them up quite frequently to ensure they didn't end up puddling around my ankles! If buying this model again I would definitely go down a size. The shortlettes with a thin band of elastic at the top feel much more secure and are a lovely fit and felt great all day, so much so that I could "forget" I was wearing them. I have an M and also an L in these and can't even tell the difference in the fit, in terms of how they feel on my body. I would order either the M or L if ordering this model again. All are beautifully made with lovely fabric - it's just the fit that I had an issue with on the two with the wide lace across the top.

Undersummers are so awesome! I love them! I have a half slip that I have had forever! It did what I wanted it to do, but since I have discovered Undersummers, I have said goodbye to the slip!

Love the slip shorts, will be ordering! Great quality.


I hate giving a 3

I hate giving a 3 star because I love SummerUnders, however the quality control needs a tweak. The same size is NOT the same size, there is as much as an inch difference in leg length and from crotch to waist between pairs. I have quite a few pairs and for the price I expect better/accurate sizing! If these were $9.00 a pair panties I would not be so critical, after all you usually get what you pay for. In this case, for this price, I expect a 4X to BE a 4X...not a shorter 4X or a tighter 4X or a looser 4X. I think the quality control of production needs to be better. It hasn’t stopped me from buying them, though! They are a problem solver for sure.

Where have these been all

Where have these been all my life?? I've been wearing thick yoga/bike shorts under my skirts for decades. Now I can feel pretty from head to toe with these amazing slip shorts. They're really soft, thin, breathable & comfortable. And I love all the different colors & styles. I'm def6a customer for life!!

They color is gorgeous and the feel divine. They run a little large. But I'll get more just in the next smaller size.

I love my shortlette’s. They are perfect. They don’t ride, don’t inch don’t but yet don’t squeeze you don’t pinch or bind. And yet don’t let your legs chafe. Modern marvel for those of us that need them

I love them. It is

I love them. It is so nice to have an option that reduce thigh friction but not a stomach compression. I have enjoyed using them in hot weather. They dry quickly washing and rewearing. It is nice to neutral and colorful options to wear with dresses. Will be ordering again the future.

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?
