True through and through

Fit was true to size, customer service noticed when I accidently added a smaller one to my cart and contacted me immediately! Great service, I love this product as I enjoy wearing skirts and dresses in the summer but the thigh rub was no fun... Thank you Undersummers

Not very comfortable

I have only worn/washed one of the three I bought; undecided what to do with others. First wearing, the stitching in the crotch irritated my skin but after the second washing that issue went away. They are very well made; maybe if I tried small instead of medium I would like them but I followed sizing guidelines on the website. They're too pricey to be just okay.

Love my purchase

I am extremely satisfied with my purchase. I would probably size down for my next purchase. Yes, I will be purchasing again !

Fusion Shortlette

This is the first time ordering these. I ordered the white and pink in the 7” to wear under summer light weight skirts and short dresses instead of leggings. They are a good length , fit well and pretty. I will be ordering the summer pink and lilac. I would recommend these.

I need every color now!

I bought these to try since another brand I had worn for years quit making my size. I wish I had switched to these a lot sooner! They're soft, no inner thigh seam and didn't ride up my legs as I moved. They did roll down slightly at the waist, but I think that's more my build than a problem with the short.

I wore them under a summer dress and I liked them. I can’t wear them as underwear since I have to wear leak protection panty liners, but they are super comfy worn over panty.

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?
