Love these—make summer dresswear perfect

Love it!

I love dresses but always have to worry about chafing and wearing tight shapers. The under summers have changed that! They are so comfortable and airy. No excessive sweating and more importantly, no chafing! Thank you! I highly recommend this to anyone that enjoys being comfortable in a dress or skirt.

Lovely summer colors

Excited to make my annual Undersummers order, purchased the yellow pair and the bright blue pair. The 9" version is a must-have for no crotch creep, as I hate it when anything rides up and bunches. I've work the yellow pair so far and am pleased with how it wears and doesn't leave me chafing. Hoping they bring back the thicker ones in the fall, sometimes the thin ones still don't do the trick.

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?
