Please improve on the waistband

In addition to the 9” Lace Shortlette Slipshort, I also purchased the Classic 6.5” Shortlette. . I much prefer the elastic waistband on the classic style. I find that the lace band on the 9” is very short-waisted and sets well below the actual waist. I always feels like it is slipping down. Not anywhere near as comfortable as the traditional elastic waistband on your Classic shortlette.

No More Riding Up Thighs!

OMG these are the most comfortable undergarments I’ve ever worn! No compression and no riding up my thighs! I’ve always had to stop and pull down my compression undergarments in public! Not with these! They glide right along with me when I walk!!! And they are not hot to wear in the summer!!! Fabric is lightweight. Love wearing these under my maxi dresses in the summer!

Absolutely love these! I don’t use them under dresses or what is advertised but instead use them under my scrubs to prevent chaffing from the inseam of the scrub pants. They don’t ride up or slip around at all. Very breathable so no issues with anything being to hot!

Love it

I have been wearing undersummer slip short for years and love it. Really protects from chafing.

Loved them. Hardly even knew

Loved them. Hardly even knew they were there EXCEPT for no chub rub!!! Is there a shorter length? I would like some to wear under shorts.

Hi! We do have several options in shorter lengths, you might like the Fusion 7" or Classic Shortlettes as well :)

I love my undersummers, comfortably

I love my undersummers, comfortably wearing dresses and skirts in summer is life changing. Perhaps have not yet got the correct size, as the L's still slip down a little. My only discontent is the size of the crotch - its so small that it disappears into the intimate areas! - which is not very comfortable. I have attempted to alter a couple of my older pairs by replacing the crotch piece with a larger one - the result is more comfortable - but the centre seam still pulls in to the intimate areas!.

I am giving these 3

I am giving these 3 stars because while the product is well made, the size is different from my last order. The same size and style is smaller than what I purchased before. I have compared the new with the old, and the new is smaller, and therefore not as comfortable.

Great shortlette, super comfy and

Great shortlette, super comfy and light weight.

These did help prevent chaffing,

These did help prevent chaffing, I just wish there was a higher quality fabric, especially for in between the thigh area. After a few hours of walking the material started piling on the first day I wore them.

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?
