I was sent this dress from Plum and Pigeon, an etsy shop that sells handmade, vintage inspired clothing. This polka dot dress is well-made, it has a side zip, two collars, lace edging etc. The cotton feels like a lovely quality too. It's really reasonable too - a handmade British dress for £55!!
I wouldn't call it a "repro" dress, its pretty short, and not a vintage style length at all. I'm about 5ft5, and its above my knees. I do like how it fits my boobs though, this is a size 10, and the buttons sit nicely over the bust (something I struggle with).
