Beating the New Jersey Humidity

These were so comfortable and made wearing a sundress in the WORST Jersey humidity no issue. Usually a dress in the summer months is impossible but with my undersummers I will change my summer clothing options to more sundresses! Thanks for a great product

My summer saviour!

The actual shorts themself are amaaaazing. Breathable, classy, comfy and they save my Thighs from the angst of chafing! The only thing I would be happy to see improvement on is delivery with a courier to Canada where you pay minimal import fees upfront (like DHL) rather than an obscene amount of COD when they arrive.

Thanks for giving me dresses/skirts back!

Love them! I feel like I can comfortably wear skirts and dresses again. They do not ride upon the legs at all. I will definitely buy more!

Better than I expected

Bought 2 of these and they are so so light and super comfortable, I wear them by themselves at home now because of how comfy they are. I was a bit worried about the pricepoint but they are so worth it, love them!

Very comfortable and light, they feel like a slip. I'm only 5"4 I wish they were about an 1" shorter.

I think mine are a little big, but I like them. They are cool and lightweight, and the lace looks cute peeking out from shorts. And my thighs remain rub-free! I’m going to order more but I might try a different size.

I love these! I bought

I love these! I bought them for traveling so I could wear dresses while doing sightseeing and I found these to be soooo comfortable. I will be buying more!

I tried these at my

I tried these at my daughter's suggestion. I generally don't have issues with thigh chafing, but finding a half-slip in my size has been difficult these days. These slipshorts fit the bill -- they prevent closer-fitting dresses from clinging where they shouldn't.

Absolutely love them! This is

Absolutely love them! This is my second pair. They are comfortable and I feel confident that I'm covered up if my dress rides up a bit.

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?
