Beautiful prom dress

Selling my prom dress from last year. The dress is in perfect condition except for a few missing sequins in the front (hardly noticeable and shown in last picture) which can be easily fixed at any alteration place. The dress is one shoulder, beautiful coral color, has a slit (left leg), and has a mini train. I bought this dress at a boutique for around $500 and also got matching earrings at the same boutique and the color is spot on to the dress. I wore nude heels but I think gold heels would also look good. The dress is a size 6 but was a little big on me in the top ( I’m a true size 6). I definitely think that a bigger/smaller size can fit in this dress with the proper alterations. The only alternation made on the dress was shortening the shoulder strap to help make the bust area fit better so nothing major. At the time I was 5’4 and probably in 4inch heels (so 5’8 with heels) and the length was perfect I would like to try and sell the dress between $425-400 since it’s in perfect condition besides what’s stated above, it was only worn once, has very minimal alterations, and it would also help to cover the shipping since the dress has some weight to it (the dress was not heavy on). Please feel free to ask any questions and send your best price!
