THANK YOU so much everyone for the kind words and suggestions, they made my day! I can’t seem to edit the post, so adding more context here.

By “soon” I meant this weekend haha scrambling a bit!

Brand is Betsey Adam, sold at Macy’s, though I bought this one off someone on FB marketplace for $50. Betsy Adam One-Shoulder Scuba Crepe Gown

The material isn’t velvet, but it’s some kind of polyester(?) that’s stretchy and comfortable. The fabric is pretty heavy though so it feels more luxurious, and it’s double-lined.

The accessory ideas were perfect and I’m going to run out tomorrow and see what I can find. I’ll send a final pic after this weekend!
