Love the Lilac

Love the 7" length - perfect. Not too long for a shorter hemline, not too short that roll up!

Silky and comfy

Silky, light, long enough to cover my inner thighs so they don’t rub together - love them

I am so impressed with undersummers! I was a little skeptical at first because of the price. I've worn less expensive slip shorts from Amazon and Jockey and they seemed to work fine, but I was curious about these because I heard very good things about them. This pair is great (I ordered 3). Love the waist - doesn't give me a muffin top. The legs don't ride up and they are so soft and comfortable. The other thing I am thrilled about is I am also a Houston areaschool based SLP that loves wearing skirts and dresses. I had no idea Carrie Rae was an SLP and I love supporting a woman owned business. Also very impressed with your customer service. I thought my package was lost (my fault for entering an incorrect address) and the company was going to replace them free of charge before a neighbor returned missing package to me. Overall. I highly recommend these!

Welcome back to Summer!

Quick turnaround got my lilac shortlettes to me in time for Mother's Day. Customer service was swift to respond and courteous when I had a question about my order. Where have they been all my life? I love this product.

Best undershorts ever!

I absolutely love these. They are so comfortable. Not binding at all. I love the lace bottoms and the lilac color is very feminine. They completely prevent chub rub, which is exactly why I got them.


The only reason I did

The only reason I did not give a 5 star is because there is a size lacking. The one between XL and 2X, which would be a 16-18. XL is a 16 and 2X is a 20. I wear Women's 18-20, which is usually a 1X. These fit nicely but just a little bit looser than I would like them to be. The quality is nice and the colors are lovely.

I love the feel of

I love the feel of the fabric as always. I just wish they were longer. Didn't realize they were too short, they roll up on my thighs.☹

I wore my Fusion Shortlettes

I wore my Fusion Shortlettes today for the first time, and I love them! They stayed put (no drooping!), kept me cool in my overly hot office, and were very comfortable, I'm ordering another pair today.

I ordered a size too

I ordered a size too small and the company handled it well. I got the kind with the lace around the legs and sometimes it still feels a little too tight. Otherwise, a great product.

These are soooo comfortable. I

These are soooo comfortable. I do not wear shorts so I almost always have a skirt or dress on. As I like full skirts, these are a life saver, as far as my underwear is concerned. I will buy more.

Claire P.

Cute but Slippy

Bought these along with another pair in a different cut. These ones I feel are bigger, as they are not as secure on my waist and they slip down. The slipping wouldn't be a big deal, but when they ride low the lace gapes, which isn't as flattering. But the colour is great, getting lots of compliments today.

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?
