Where can I get replacement dress straps from?

[chicaguapa]

I've bought a lovely strapless Monsoon dress from eBay and saw that it has little loops inside for some straps. Obviously the seller has lost these and they weren't mentioned in the listing so I don't mind. But I'd quite like to get some and wear it with straps if that's an option.

It's just a plain black dress with netting over. Any idea where I could get some? Do you think bra straps would work?
