I don't have the style you inquired about, but I do have a BRAND NEW GORGEOUS Melissa Sweet dress that is VERY similar in style and fit to the ones you are looking for. It's from her 2006 line and since has been discontinued, but is very similar in style and fit. It's a size 8. It's never been altered or worn. I just bought two dresses and I have to part with one and I'm willing to do so at a VERY good price. Didn't know if you would be interested.
Here's the official description.
Beautiful, Brand New, Never Been Worn authentic Melissa Sweet "Romina" wedding dress. This dress is a strapless A-line natural waist with French Lace Bands over Ivory Silk Organza. The designer label and size label are intact. It's a size 8 on the tag Bust 36.0", Waist 28.0", Hips 38.0". It has never been altered and I usually wear a size 4 or 6 in street clothes. This dress is in PERFECT condition. It is very light and flowy. Extremely comfortable. Dress retailed for $4200.00. I was one of THOSE that went over budget with indecisiveness and bought two dresses and looking to sell one ASAP. $1500 OBO. Wiling to negotiate.
Price is $2000 which includes a veil ($550) that was made specially with the same lace that is on the dress. Please reply with your email address and I will send a picture. The color is ivory. Thanks!
