Long for short people

I'm short and didn't realize just how long 15" is, but otherwise I love Undersummers underwear.

Long Anti Thigh Chafing Underwear 15" Length - (Beige

Performed satisfactory , no riding up on legs , no rolling at waist line. Size I believe is true. I did find these a little warm on the hot day that I worm them so they may be better suited for the cool days of fall and spring.

This item is one of the most comfortable undergarments I've ever worn. The material is very soft and durable. The comfort really causes outer garments to lay so much better and flow smoothly. A lovely addition to any wardrobe.

Long Underwear

Wore these under the same slinky knit fabric pants I wore with the Slipshort that I also posted about. I enjoyed the length even thoug it is summertime. Kept me cool and most important to me, helped to keep the pants from being too clingy. Undersummers are the only brand where I spend this kind of money on "underwear" (they are truly more than just underwear).

Way to big!

First time customer. Way to big! Ordered the recommended size per measurements and are way too big. Contacted Undersummers and they are being very helpfully and helping me to get fitted into a different pair.

I have purchased various styles and lengths of Undersummers. I love the longer 15” length of this anti thigh chafing underwear, but find the waistband to be loose and too low. Would prefer an option for an actual waistband (at the waist) like your Classic 6..5” Shortlette, instead. Still giving it 5 stars.

Overall, it is what I was looking for, since I wear dresses and skirts often. Please offer this with a Classic waistband!

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!!

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?
