The original has been sold out on the ta ta towel website but my ta ta's wanted one so I did what maybe was the next best thing: get a knockoff.
I ordered my knockoff and it came on a slow boat from China and during the 5 week transit time my original arrived two days later. What's the difference in a $12 version vs. the $45 version? turns out, quite a bit. My disclaimer is I did not get this product for underboob sweat. I wanted a break from having a tight band around my chest during waking hours. I am a natural born E cup and 5'11 tall. All this info will come into play as we get into more detail.
I ordered both in size MEDIUM for DDD-E (I think those two cup sizes mean the same thing. I used to sell lingerie as my first job).
The knockoff has a cotton-ish lining out of an inexpensive liner material you might use to make a pattern from. It's not uncomfortable though. What is an issue is the fact that it is not adjustable around your neck. I need to shorten it even at my height. The cup size was perfect, offers a little support (on a scale of 1-10 support is a 3-4). I got a little crafty and tied a knot in the back to shorten it and while that helped it created some discomfort with the knot digging into my spine. I vacuumed, played with my new kitten, washed dishes, cooked meals and did some writing work in it and it stayed comfortably in place but there is bounce and movement. Certainly feels more natural than a choking bra which is why I wanted it. Win.
The original is really quite different in design, structure, and material. It's much softer and better quality of super soft absorbent cotton terry. The neck adjuster is very comfortable and easy to maneuver without having to look at it. Just reach back and pull into the position you want. Again, even at my height with natural breasts I had to pull it a good 5" tighter. the cup itself is about 20% smaller than the knockoff but still fits me well and a larger size I believe would be too roomy for my ta ta's. It withstood all the in home activities as above with the same endurance level.
Verdict: If it's in your budget get the original because you're going to be wearing it every day. Just skip dinner out this month. Stay in and cook in your ta ta towel.
