My quarantine buddies

I love these Undersummer garments! I wear them everyday while I work from home. They are comfortable and keep my friendly thighs from sweating and sticking together.

Great Bloomers Batman!!!

These are super nice shortlets! I love them and I especially love all the fun, bright colors they come in! They fit me perfect as I have large thighs and sometimes its hard to find pants that fit right. These are great and I will be buying some more pairs. I wear alot of dresses in summer and these shortlets are perfect for avoiding chaffing!

Where have these been

All my life? I never wore skirts or dresses because of chafing. But Undersummers have changed my life. The unique front seams make the fit unbelievable. You gotta get some!

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?
