I like these. They do

I like these. They do the job you want them to and don't leave you feeling overheated or sticky.


These are my 6th pair

These are my 6th pair of undersummers!! I love that I can wear dresses again. Not only that, but I now use them as summer sleepwear:)


These are comfortable and do

These are comfortable and do the job they are designed for. The only reason I gave them a 4 is because even the shortest ones have to be hemmed for me. I’m 5’0”. Overall, I’m happy with them and will probably order again.


Fun colors and functions great.

Fun colors and functions great. My only issue is that they are a bit warm. Don't really breathe, so on the really hot days in Texas they are a little uncomfortable.

These are perfect! The lightest

These are perfect! The lightest material for summer and so adorable. The colors are bright and so cute under my dresses. I don't know why I waited so long to purchase these.

3 stars for the color

3 stars for the color and the comfortable fabric, but the fit isn't great. The waist band is thin so it rolls down pretty much immediately. If you pull them up to be high waisted they don't roll down anymore, but then they're too short and don't protect from chafing.

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?
