Excellent product!

Undersummers ----- where have you been all my life?! ! At 73 I FINALLY find some lingerie to comfortably wear AND protect me from embarrassing skirt flips (& falls, to be truthful). In hellish heat I can slip on a whisper thin mumu and sandals and BE COMFORTABLE! LOVE this invention! ! !

More comfortable than I expected.

As a rule I never wear nylon underwear. However, these slipshorts were surprisingly comfortable, even on a hot and humid day. Looks like I'll be getting a couple more pairs!

I love my undersummers!

I’ve worn them once on a moderately warm day. I was amazed. There was no creeping of the legs - they were cool- I was able to wear this lightweight sweater dress here on Arizona. Love them and am recommending them to others!!

I recently hurt my knee

I recently hurt my knee and was in a brace while waiting for surgery. The brace hurt the other thigh because it was so rough. The slipshorts saved the day because they prevented it from touching and rubbing. They also protected my modesty when people need to see the brace. After two months of using wearing the in such rough conditions, all of my pairs are still in perfect condition!

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?
