Turquoise Color Little Black Dresses Short/Mini Empire (4 items)

I just had a quick question, I am having my wedding in September of this year and I am having my bridesmaids order their dresses from your website as you have some very gorgeous and affordable dresses. My question was regarding how many you have in stock or if you have an unlimited amount. Of course with a wedding everyone wants to lose weight so we were all wondering if it would be safe to wait until about a month, month and a half before to order so they have that time to lose weight and beable to get the size that they need or if you have only a certain amount and would need to order them now. The dress is the champaign casual a-line sabrina chiffon ruching party dress. Any information will be greatly appreciated, Thanks!
