Leeloo suspenders

[Starfleet]

Hi. I'm a cosplay beginner and wanting to make Leeloos suspenders. Would using something like Trylon liquid latex rubber with thickener added poured into a mould work?
Thanks guys

I apologize for going off track but you could also use something like L200 eva foam as an option.

I'll echo that L200 is great for replicating thicker clothing like straps or leather.
