2. Christy Dawn
Best For | Boho-inspired wedding dresses
Based In | Los Angeles, CA
Christy Dawn designs are inspired by the consistent landscape and lifestyle of California (and Mother Earth!). The designer says, “There is something beyond the fabric I hold on to. Something honest about vintage. Something classic. Something timeless, that reminds me of home.” Every piece is handmade by artisans using either organic cotton or deadstock fabric to minimize their environmental footprint. They only ever sew a limited number of pieces, and the designs reflects a feminine, flowy, boho vibe.
Customer Review | “What an absolutely stunning dress! I wore the Fitzgerald for my wedding reception in Washington and will be wearing again when we host our New Jersey reception in July, and I’m so happy I get to wear her twice because I felt like a whimsical princess all day in her! The silk is so soft to the touch and the lace details are as beautiful as pictured! The fit was almost perfect, but there was an odd amount of extra fabric by the chest area on the side without the zipper which was easily altered. Other than that, the dress fit like a glove!” – Katelyn C. (Read all reviews.)

It held up great (minimal wrinkling) and let me be totally present instead of worrying about boning or straps all day.
