The Original Classic Shortlette is a better than bike short solution for wearing under dresses.  We hear the comment all the time;  I wear a bike short under my skirts and dresses.  CarrieRae did too... for many years, however bike shorts are thick, hot, and have a bulky waist band.  They are not a single layer solution without the cotton gusset.  CarrieRae designed the Shortlette®️ to be a lightweight, cool, breathable solution that did not ride up or roll when wearing.  This black thigh protection short is figure flattering, comfortable, and cute enough to show!

Really comfortable. At first I

Really comfortable. At first I thought my Lycra bike shorts were better, but after wearing these for a full day in humid hot weather these shorts are lighter, less sweatier, don't ride up my legs and make wearing dresses very easy. International package tracking wasn't great (I'm outside US), but package took reasonable amount of time to arrive.

Undersummers were recommended to me

Undersummers were recommended to me by a friend and I am so pleased I followed her advice. My new undershorts are so comfortable, cool and easy to wear. I love that they don't ride up, that they don't dig in, that they make wearing skirts a pleasure and not a pain. I will definitely be recommending to my friends.

The "swishing" noise did put

The "swishing" noise did put me off at first, but I didn't really notice it throughout the day. The comfort and ease of the classic design will make me come back for more of these. I'm hoping the fun colors come back in stock.

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?
