    Best Shaper Ever Used!

    Posted by Cyndi on Jun 13th 2021

    I bought the HB7 Low Waist Above Knee TBL shaper to help smooth out certain lower areas in a very fitting dress for my boyfriend's birthday. I was worried because I never do low waist ANYTHING since I am tall and wide, but the dress had a low back which I could not use a full shaper for, so I took a chance with Yahaira. AND IT WAS THE BEST RISK I EVER TOOK! The low waist didn't roll down as other shapers do and the legs didn't roll up, so no ugly noticeable creases or unflattering areas. The fact that it did does not flatten the booty, is also a major plus! I am currently 4 months pregnant and am still able to use the shaper to support me. To my surprise, it's still comfortable, but I know I should not wear it, so I have just ordered the maternity shaper and cannot wait to wear to support my shape during this first pregnancy! I have never felt so supported while also being so comfortable! I love this product and cannot wait to get my newest purchase!

    I LOVE this shaper. It doesn’t bulge at the waist like most shapers. I think that was my main concern. Shipping was fast I’m a happy customer

    Best Shapewear

    Posted by Dulce on Apr 22nd 2021

    I have bought from different brands and none seem to do what this shapewear does. It lifts your butt and hides the tummy. I already bought 2. The short and knee. If you're thinking about it go for it!

    Happy But #7

    Posted by Bonnie on Oct 21st 2020

    True to size, I am 5 feet and have a short torso. This is the first shape wear that fits perfectly. I work in healthcare and work long hours and this shape wear can be worn for many hours and you will forget that you have it on.

    Perfect but size up

    Posted by Tracy on Oct 4th 2020

    After so many videos, reviews I decided to take the plunge and buy the low waist one. I’m 5’2, have a normal to shorter torso. I’m 120lbs. I was told to order a small since I wear 4-6 jeans but went with the MEDIUM and I’m SO glad that I did. The small would have been super uncomfortable and just way too tight for my liking. I have a size 27-29 waist. If you’re close to my measurements which may seem small, trust me and get the medium unless you really like being squeezed super tight. The medium still hugs me tight, lifts NICE and give me all the curves in the right places. Very pleased!
