I had a tip from a reader (thank you Selena!) that BlackRose had several dresses available for free at their mainstore, so off I went to see what goodies I could find!
IN ALL PICTURES
.HAIR. Mermaid Motel by Little Bones [FREE / Group Gift / Free to Join - Check Notices]
.SKIN. Emma (Peche) by Essences [L$70 / The Dressing Room Fusion]
.JEWELLERY. Big Pearl Set by Yokana [L$10 / Opening Gift]
.DRESS. Halter Dress (Animal Print) by BlackRose [FREE / Gift 3]
.OUTFIT. Cropped Top and Plaid Skirt by BlackRose [FREE / Gift 1]
.DRESS. Turtleneck Dress by BlackRose [FREE / Gift 2]
These dresses are available also, but you will find them on shelves to the left of the main entrance if you are stood looking out of the store. I hope that makes sense!
