Last time i looked, Dawn & Dusk didn't have much of a wardrobe. That surprised me because Dawn has been around for 2 years.

2 issues. 1. Vendors were expecting V4 level of sales from a brand new figure, which was a tad bit unrealistic. Most of them made 1 product, it didn't sell as well as they had hoped, so they decided to pass on the figure. 2. Dawn didn't ship with much in the way of morphs when she launched. Once the morph packs were made available, she was as versatile as V4. Same size, and same weird body proportions (that everyone apparently likes) as V4, but can take advantage of Poser 9+ tech.

With Poser, clothing has been decoupled from figures for a while now - If you don't have Poser Pro 2014, you still have Wardrobe Wizard built into Poser - Pick up the V4 & Dawn modules over at PhilC.net & have at it.

If you have Poser 2014, Pick up Lyrra's Fitting Room Magnets for Dawn. You can convert V4's clothing to Dawn in less than 30 seconds.
