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!

Love them!

I really wanted to love these, but just didn't. I wish the waistband at the top was wider. The tiny, narrow waistband just annoys me and isn't comfortable. Also, I wish they offered a shorter version. Even the shortest ones are too long if you're wearing a short dress. They also just seemed pretty cheaply made, for the price you pay. I will not purchase again. I have cute yoga shorts that work better under my dresses. Wasn't impressed with their customer service either.

Loving my slip short

As I play golf in the hot and humid south this summer and try to look fashionable in a skort, I am grateful to find and American made product that feels great and achieves the problem of chafing. The inner ****** tha come in most skorts just don’t do the trick. Thank you Undersummers!!!

Not exactly what I thought it would be

It made me hotter and it was not that comfortable to wear.

Great Addition to My Summer Wardrobe

Really pleased with the fit and wearability of this best sellers! I've enjoyed it around the house with a long shirt and under a dress to go out. In this hot summer heat, it's been a welcome addition to my outfits so I can wear cooler dresses!

Game Changer

My inner thighs have seen it all: deodorant, bike shorts, workout shorts, other brands of "shortlettes," anti-chafe sticks, etc. These will be the last product I ever purchase to save my inner thighs. They are absolute perfection. Lightweight fabric that you literally CANNOT tell you're wearing, the slip-like fabric is a dream under any type of dress, helping it move smoothly overtop the shortlettes. The waistband doesn't dig or ride too high or fold down. I purhased 2 pairs initially and just bought 3 more. Total game changer for girls whose thighs rub together! Thank you Undersummers!!

Super soft, but got wrong size

I was reading reviews and took measurements, but still managed to get the incorrect size. The reviews all said that the garments are true to size. But with us curvy girls, where your curves are can make a big difference. I’ve got the classic hour glass figure and probably need to go with the next size down. And due to COVID I cannot return the package I opened. Other than that, great product.

Wearing all the time

Perfect for under dark fabric: Classic Shortlette Anti Chafing Slipshort 6.5" Length (Black)

I own a few pair of Undersummers in lighter colors because I love their products! I bought the black shortlette to wear under my many black dresses. I found that the black set does fit a bit snugger than the lighter colors. Not uncomfortably so, just as a comparison. You may want to size up if you're between sizes. I appreciate the lightweight feel of the material - remember, it's not shapewear - yay! The seam placement and fabric combine to give coverage while you barely notice you're wearing them. The best part is no chafing! I highly recommend these shortlettes!

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?
