Royal blue shirt chafing

What a difference from wearing another type of pants or slips. They are a thing of the past. Your product is so comfortable- you know even realize you have them on.♥️

No complaints

I have multiple pairs for these reasons: wash well, hang dry quickly, legs stay down, waist stays up, overall nonbinding.

LOVE them ALL!

I have acquired a rainbow of Undersummers because they are, well, EXCELLENT! I like the shortlettes (with or without lace). This summer I have worn my Undersummers every single day—under dresses, pants, and even my hiking shorts. They have helped me survive the Texas summer heat (which is not easy), and they are cool, super comfortable, and, yes, CUTE! They are well made, well designed, and easy to care for. Don’t hesitate! Get a pair (or seven). :)

Awesome product

Very comfortable, beautiful color. These have changed the way I feel in skirts and feet in the summer. Highly recommend.

The slipshorts are amazing! They are not tight, yet stay in place without riding up my legs. I previously used another brand of slip short, made by a famous maker, and the Undersummers are WAY better. WAY WAY WAY better. Worth the price, love the colors, my new favorites.

Cool and comfortable

I love my under summers! I live in SC so I need a cool alternative when the heat hits with a vengeance. I find these very comfortable and breathable. They dry quickly after coming in from the heat. They don’t ride up and are not binding in any way! Highly recommended!

No More Embarrassing Moments

GREAT! I thougt I was doomed to wear men's long legged under shorts until I saw these on TV. I bought two pairs to try. I threw my men's undies away and bought three more pairs. I am sure I will be buying more. The fit is comfortable. I hardly know I am wearing them. No more embarrassing moments at the doctor's office.

A cool anniversary

I waited to wear my under summers for our special dinner out. High temperatures and very high humidity did not spoil the evening. I love your product.

Crazy In Love!

As soon as I tried a pair on, I immediately fell in love with these slipshorts! I purchased several styles, and I love them all. The colors are vibrant, all with the most comfortable fit ever! I normally wear a size XL in ladies underwear and I purchased an XL in the undersummers and they fit perfectly. I have waited years for a product with the style, quality fabric, fit, and comfort of this brand. They wash well too. Finally, I am back in my summer skirts and loving it!

Shortlette 6.5 and 9"

I don’t usually write a review but I just over these Shorlettes’, I bought both the 6.5” and the 9” Lace one - I love them both but the longer ones are better for me since I have such big legs. (230 LBs 5’9” - bought 2X). Also, Customer service was great, had a problem with incorrect size sent and they responded right away and even sent a replacement at No Charge before I even sent other one back. I would definitely buy from Undersummers again.

Beautiful color

I bought this to match a new sundress and it was perfect. The item is silly and smooth but I order a size smaller because I like a more snug fit. I had accidentally order several others in the wrong size and the return was handled efficiently.

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?
