Hi Krzysztof,

Short answer is yes...a brace under the scarf is a better design, but there is more to it than just that, there is also type of scarf, orientation, and other factors too...

Send me an email, if you want to explore this in more detail at:
tosatomo@gmail.com and I would be glad to explore it in more detail and other possible solutions as well...

Warm Regards,

j
