Swim short

I absolutely love these black swim shorts. They have great coverage. I have wore them several times swimming in the lake.

Swim shortlette

Haven’t got to go swimming yet. But just putting them on felt so comfortable. Just like the undersummer for dresses. Thank you for such a wonderful product!!

Great,comfy, wear them lots!

Wonderful. I have found I like the longer ones better than the shorter ones. Wear the swim shorts whenever I go swimming.

Great product

So very comfortable, no chafe during the hottest days. Go from normal dress in shorts straight into pool with the swim shorts. Love these products

Swim shortlette swim shorts

I really love them. The material is thin, but not see-thru. Very comfortable and dry fast too!! Although they are a bit pricey, I think they were worth it!

Nice but could be better

The concept was really nice but was disappointed when I went to wear them for The first time. There is no liner in the important areas and the fabric is very thin. I didn’t feel as confident in them as I hoped. I kept the pair I bought but wouldn’t buy again.

The swim shorts worked perfect!! I wore them under my jean shorts and couldn’t even feel them they was so comfortable. They also worked perfect with my bathing suit top and made me feel more confident.

Comfort for a active water day

No chub rub...what else can I say. Perfect for the water activities I do including hiking like activities while still wet. Wearing them to my next floor trip the end of July.

Swim shortlett

I’m happy with my purchase. These shorts do not ride up & the waist band does not roll down. They are stretchy and comfortable. I bought size large, they are pretty true to size but if unsure size up.

I can’t compare these to

I can’t compare these to others as this is the first pair I’ve purchased. I can say The lack of thickness and gauze in the crotch, shows the “divide” of your intimate area - if you know what I mean.

Nice length and stretch. Unrestricted

Nice length and stretch. Unrestricted movement, lovely silhouette for my chubby thighs!

I AM SO GLAD THESE EXIST. This is one instance where if you are between sizes I might lean smaller so you can get a bit more compression. But they are so cute and comfortable and after one of the worst chafing beach experiences without them, they are heaven sent. Have also worn them for doing a lot of sweat laden physical activity so they dry quickly. Very light weight for having such full coverage.

I am 68 years old

I am 68 years old and still enjoy swimming in the ocean and doing laps in the pool. In wearing the swim Shortlette thigh protection swim short I find I feel more comfortable and am definitely more confident in public. Thank goodness I have finally found this wonderful product.

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?
