I love my new 9” Shortlettes! They are so silky and soft. The stretch and comfort under dresses is just right, and the lace adds a touch of elegance. I have been wanting a product like this forever! I am so glad I found you!

stays in place and no chafing!

I actually reacted to your commercial - because it it solved a real problem!

I've been wearing skirts more and more this summer, but I also love to walk and walk. These are everything I'd hoped for - cool, comfortable, cute. Thank you!

Beautiful blue!

Undersummers are my favorite under dress piece! This blue is like a retro blue, love it so much!! It's so The Notebook Blue - Rachael McAdams dress ;)

Oh , the Comfort

I wear these to bed. Lightweight, perfect length so my legs don’t rub together. Cool and do not bunch up. They move with me. They are so comfortable. I own several pair.

True to size

Soft, quality, comfortable; however, it’s missing a cotton panty insert like the shorter version has. That is a big deal breaker for me.

First Purchase

I'm very satisfied with the 9" shortlette. They are lightweight and comfortable under an unlined skirt or dress. I bought them for comfort and modesty, taking the place of an old half slip I had been using. The shortlette looks nice, stays in place, and helps the garment drape properly. I occasionally must wear incontinence pads or briefs and the shortlette feels feminine and stylish. I will purchase more styles.

Lovely light shade of blue!

Not only do they look cool, they are surpisingly cool and comfortable to wear!

Love these!

I adore Undersummers. The first two pair I purchased had lace at both the top and bottom. The fusion version has lace on the thigh-edge only. Super cute. The waist seems to ride higher on the fusion version than the lace, also the 9" seems to be longer in the fusion version. These will be great for longer skirts. I think I'll try the 7" fusion and see how that works for shorter skirts. Overall, great product.

Bye bye chubrub!

I’m a lady with thighs that touch and inevitably develop friction burn without the assistance of a protective layer, ESPECIALLY in the humid summers of central TX. These undersummers are so lightweight, comfy, and unrestrictive, I feel totally comfortable running around all day without fear of needing a skin graft at the end of the day. So worth it!

I really like my new undergarments.They are very comfortable and pretty . For myself I wish they were 11"long instead of 9" My legs are real big around and length would be better. I do love them though. Thank you

Can’t live without

My 3rd pair of Undersummers. Can’t believe I went decades without them. No painful struggle to put on, no indentations all over from ******* you in to tight. Best of all, no chaffing! I walk for hours, dance, climb stairs in pretty summer dresses or skirts. Just feeling good, and able to move freely. Curving girls best friends❤️

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?
