Off-the-Shoulder Sweater Dress, 230 pieces for each color except for the red variation which was a 2006 IFDC exclusive of 150 pieces (retail price $20)- these dresses were sold without any other accessories but there was a separate accessory set sold around the same time that was specifically coordinated to go with these dresses.

All 4 color variations: coral, red, white, sky blue.

Coordinating Accessory Set, 230 pieces (retail price $24)- I don't own this set but RC did state that it was designed to be used with the off-the-shoulder dresses. Here are RC's promo pic and a NRFB pic:

Randall also made 4 color variations of this dress for 16" dolls. The colors were camel, lavender, pistachio and rose. I accidentally bought the rose one years ago and found that it fits 12" dolls ok. It's longer and has a wider cowl neck. I don't have any 16" dolls to model so here it is on Cher who is on a ModelMuse Barbie body.

And just for comparison's sake, here you can the 1/6-scale and the 1/4-scale dresses together.

Hopefully more sweater separates coming next week although I have a doll show next weekend and then Easter the weekend after that so there might end up being a short hiatus before I can get back to re-dressing.
