Love the comfort!

Overall doing great! It is hot and humid here and the length is perfect for no chafing!

Feeling confident!

I love the soft silky feel of under summers. Not so tight it cuts off your circulation not so loose that feel they could slip off. Simply perfect fit.

Great for travel

I purchased these to wear on a trip last summer through 5 countries. We walked 6-10 miles a day touring. They never rode up and were comfortable and cool all day. Since we traveled with backpacks they were easy to wash and dried overnight. Love!!

Pale blue undersummers...

They fit quite well and I really like having them to wear under my dresses.

Comfy and Cool

I love the shortlettes! Perfect under dresses or loose clothing. Cool. They are now my summer standard. Thank you!

My new favorite underwear

I have big thighs and I live in Phoenix so I can honestly say I've put these to the test repeatedly and they passed with flying colors. They're very lightweight, stay put without being too tight, and keep me surprisingly cool in 100°+ weather. I was hesitant at first to spend so much money on a single pair of undershorts but these are worth every penny. I'll definitely be buying more.

Shorlette fits the Promise

I love this under my dresses and skirts! It is comfortable, well designed, silky on the skin, with nice finishes on all the seams, and most importantly the lace is silky, too. One request: please make this in one more smaller size overall (2 to 4). It's a little large for us petites, but we like a slip-lined shape under our dresses with our bottoms covered in the breezes, too!

These are Wonderful!

I love these. They slide on easily and prevent the dreaded chub rub.

Love these!

Perfect for under dresses and comfortable even in hot weather. The waistband on this version tends to show through more that others when worn with slim fitting dresses so giving it 4 stars instead of 5. Personally I prefer the lace or athletic versions instead.

I chose too snugs

This fits but is very snug. Need to stay with 5x. I have purchased several and wear them most days of the week.

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?
