Bridesmaid/Groomsmen Colour

hey guys! my wedding is 11/27; everyone says im too early looking for dresses/suits, but I went to 3 different stores now looking for turquoise and I have yet to find a turquoise dress for the bridesmaids. I’ve been to Atiana’s and David’s Bridal in Milford, and Casa Tony in Hartford. yes I’m early, but imagine if I started next year and still have the same problem ): can someone help me look for turquoise dresses in CT in-store? I know I can order it on Amazon/online, but that’ll be my last option. I’m even willing to go to new york. as per the groomsmen theyre going between October-November, so i wouldnt know if we’d have trouble looking for them as we are for the bridesmaids. (the guys will wear turquoise inside shirts). if anyone has advice for the shirts for the guys as well I’ll take it! thank you
