I rushed out and purchased this and tried it on with various shirts.

There are three main problems with this item:

1.) you probably have to buy a new bra so that you get one with straps that you can let out enough.  My standard bra was too tight even after letting the straps out all the way.  It made it extremely tight.  And you have to tighted the bra hooks due to the fact that it will sag in the back since you pulled the straps close together.

2.)  The item protrudes out of the small of your back when you lean over.  It sits in the small of your back for most shirts and is great if you never lean over.  It will leave people wondering why you have a hump back there. I do not ear tight clothes so I was shocked that it was so noticable. Maybe it should be more flexible to help this. It was not bendable at all so you can shape it to you better.

3.)  Now you have a strap problem in the front.  The straps were way up on my neck and I had to tuck them in over and over.  I adjusted where I could and it was still a problem.

Try it but be forwarned.  It is not easy to put on like they show on t.v. and it can be uncomforable.  You would be 100% better off buying a multipurpose bra with straps you can move around.
