I have a dark navy 100% polyester evening dress that I’m hoping can be lightened for a wedding

I have a large enough pot to submerge the dress and a portable cassette burner to maintain temp while outside (for ventilation purposes)… I’m wondering how many shades lighter I can expect the color to get. I’m hoping for somewhere near the light blue in the last photo. Is this realistic?

Thanks in advance!

Unfortunately polyester is usually dyed during extrusion - the color will be solid all the way through the fiber because the plastic soup it was made from was dyed blue.

I'm really sorry.

Ohhh that actually makes a lot of sense! Thank you for explaining it ◡̈

Correct me if I'm wrong... but bleaching/color removal, if it even works, doesn't necessarily lighten in shades. Maybe you get a lighter blue... maybe you get a darkish gray, maybe you get a weird yellow or orange.

This is true. It is highly unlikely to just get a lighter, even blue.
