I love these! I bought them for traveling so I could wear dresses while doing sightseeing and I found these to be soooo comfortable. I will be buying more!

I tried these at my

I tried these at my daughter's suggestion. I generally don't have issues with thigh chafing, but finding a half-slip in my size has been difficult these days. These slipshorts fit the bill -- they prevent closer-fitting dresses from clinging where they shouldn't.

Even though they are very

Even though they are very soft, the seams are not comfortable. The legs kept riding up and the lace tore the first time I tried to pull them down. The lace at the bottom of the legs just doesn't work. They became itchy when the legs would bunch up.

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?
