This is the best discovery ever!! I love everything thing about my undersummers- the fit, the length, the fabric, the silky-Ness. Now I’m wearing dresses and skirts all the time. Love them, highly recommend them. I’ll have a whole drawer full of every color soon ❤️

Awesomely long but runs large in waist

I LOVE how long and smooth these are, perfect for maxis. As always, great fabric and comfortable seams. Only downside is I had to take about 3" in at the waist. It was so large, a flap of fabric actually hung loose (away from my spine) at the back seam, and the shorts would slide down my stomach/hips almost immediately as I walked. Maybe because there's no added waist elastic like on the Fusion Shortlette 7"? It still fits my thighs and hips comfortably, but the waist felt like it wasn't as high as some of the other styles I've purchased. For reference I have big thighs, 51" hips, and 36" waist. I usually buy a 2X (slightly tight in the thigh, fits waist) or 3X (fits thigh, slightly loose on waist) in every other style I've bought. I like buying them slightly larger because when the shorts are tight on my thighs they tend to ride up, but in this instance I think sizing down would be better to get the more snug waist fit.

No roll legs - Hallelujah!

The anti-chafing shorts I have been waiting for! First pair I have found where the legs don’t roll up!! Material is soft, comfortable and cool. These fit very large in the waist - I have ordered another pair a size down to see if that helps. If not, will have taken in. Love these shorts!!

I love my garment. I have arthritis in both knees and my knees feel better when they are kept warm, that why I prefer the longer length. I wear them under dresses, to lounge in, and for pj bottoms. I use them for so much and I love them, they are super comfortable.

Just what I’d been looking for.

Finally! An end to chafed thighs when I’m wearing dresses. I’m tall and wear size 12 pants and the XXL fits perfectly.

Love these! Well worth the price. Thank you for making a longer length.

Love these longer length underwear.

Love these longer length underwear. Gave a 3 star because the price is ridiculous. I have 2 pair presently and would order more, but they are too expensive.

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?
