Downsizing wardrobe

These are a must have in my new wardrobe. I LOVE these! They make wearing a dress more comfortable. Just wish the white had pockets.

I absolutely love them. Soft, cool, non itchy and the best is that the legs stay down and are not tight. Did I say I love them. Thanks so much!!

I ordered a large. Too big. I need to return. But am excited to have the right size. The fabric was soft and will be great for summer wear.

In love!!

Extremely comfortable, fits so well, soft and stretchy! I felt so secure wearing these all day under a dress. I will definitely be buying more!

Great addition to my foundation wardrobe

I love my Undersummers. My only complaint is that after multiple wears, the legs bunch up and have to be adjusted by pulling down to lay straight. Maybe I will go down a size next time.

I purchased 2 pairs and just love the product. No bunching, the quality of the material and sewing is excellent. I had to buy a few more colors . Then shared your site with my sister in Georgia where its hot and humid and she bought 2 pairs. Thank you

This is my first pair of Undersummers. When I took them out of the package and held them up, it was reminiscent of my mother’s bloomers. I then tried them on and OMG, talk about comfortable. I’ve never felt anything like this. Walked around the house with them on. No riding up!! They fit perfectly. I haven’t worn a dress in years but am sure going to wear one now. I couldn’t be happier. Wonderful. Will be singing praises about this product to my friends and family and certainly buying several more pairs.

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?
