I got this dress for a wedding. I bought the army green in a size small. The green is brighter than a military olive drab. Its between forest green and Kelly green maybe? I am 56 and 135lbs, and I wear a 34c. I think the bust was a tad tight. I think maybe a medium would allow for more movement and stretching, however the small had a great fit. The picture I took while I was wearing a petticoat under the dress. It added some nice flow and body. Perfect for twirling!! Hope this helps yall!
