I've worn these three times

I've worn these three times by now and each time it's just perfect for my needs. It makes me feel comfortable in my own skin when I'm wearing dresses that might accidentally show my underwear if i move my legs in just the slightest wrong way, so I'm actually a lot less tense and feel free to do whatever i like. They are also quite good underneath my yoga-dress pants--hiding the seams of my underwear and keeping my thighs effortlessly dry in heat with 90% humidity. Washes well (i stick them in a laundry bag/net under regular wash cycle in the machine & hang them to dry). No lint balls formed after washing. Silky smooth fabric. Definitely recommend.

I've tried several brands and these are the best! The waist doesn't roll. The legs stays exactly where they are supposed to be. The fabric has stretch, but doesn't stretch-out getting bigger and bigger throughout the day. In addition, the length is perfect...not too long, not too short. I can't say enough positive things about this product and company!

I love these so much that I keep buying more. I’ve never enjoyed dresses more than this summer. I won’t wear a dress without them. I highly recommend!

I love them, but I may have the wrong size. They ride up, not staying put. Not too sure, I’d love to talk to customers service about it. Thanks!

The best slipshorts for wearing

The best slipshorts for wearing under dresses. They are very comfortable to wear especially in very warm weather and no chub rub at all. Definitely worth buying!

I like them. They r a bit loose in some areas and I dislike the thick lines that run down the front of the thigh. Other that that, they are great to stop thigh rubbing.

I used the sizing chart

I used the sizing chart but they are bigger than expected and more see thru than I'd like. I don't think I'd wear them in lieu of underwear because of their sheerness. I should have saved the packaging to return them but I didn't.

Extremely comfortable. Undersummers never roll

Extremely comfortable. Undersummers never roll or ride up like so many compression shorts do. Perfect under dresses and skirts.

I love these and am

I love these and am 100% hooked - can’t wear a dress without them when going with no tights in summer! NOTE: I have a pair from years ago and sizing seems to have changed. My size M from past is quite a bit larger than current size M. Beware if you are comparing to older pair. With this being said I do think they run true to size (ran big before, in my opinion).

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?
