What fabric for the sleeves?

[Miljah]

Am making this dress, the version with the short sleeves. The fabrics I am using are a mid weight black polyester, and black sequinned polyester. The front and back panels will be sequinned, the dress sides black- but should the sleeves be black or sequinned?

Sequins; but you could make both and see what looks best!

I would go with black as that will 'frame' the dress and provide contrast for the body of the dress. Sounds like it will be an amazing dress

What about black chiffon with an added Sparkly trim

This comes in royal blue and black and could be a nice trim or detail somehow

You could make a matching hair flower and attach to a hair clip
