01
Your tummy under a T-shirt
Your T-shirt falls smoothly again.
A regular brief stops below your tummy, and you can see that under a T-shirt. The HighFitSlips comes up high, over your tummy.
No more hiding under loose blouses.

Frequently asked questions
A question before you order?
Is your question not listed?
Email us at info@guillyunderwear.com. You usually get an answer within a day.
Which size should I choose?
Choose the size you usually wear. Unsure between two sizes, or about the fit around your legs? Email us at info@guillyunderwear.com and we’ll help you choose.
Is this shapewear?
Not really. It is a brief like you are used to, but higher and made of thicker fabric. No boning, no harness. It gives a little more support around your tummy, so your tummy shows less under a T-shirt.
How thick is the fabric?
Thicker than a regular brief. It is mostly cotton, and that firmness gives the high waistband its shape.
Can you see it under my clothes?
Under most clothes it sits smoothly. Under thin or tight fabric the waistband may show.
Does it roll down or slip?
It has a high, fixed waistband that is meant to stay in place. Does it still roll down or slip for you? Email us at info@guillyunderwear.com and we’ll look into it together.
Is it leak-proof?
No. The HighFitSlips is cotton underwear and is not made for bladder leakage.
How many pieces do I get?
With 2+3 you get 5 pieces, with 5+5 you get 10 pieces. For each row you choose the colour and the size, so you can mix colours.
How do I wash it?
At 40 degrees, ideally inside out. No fabric softener and no bleach.
When will I receive my order?
Within 5 to 10 working days. As soon as your parcel is on its way, you receive a tracking code by email.
