Washing the Garden Party dress? And two changes I made…

Hi there! I just finished two Garden Party dresses and I love them! Just wondering if anyone has washed theirs yet? I'm a little concerned that weird things will happen to the pretty gathered bodice with washing. Would love to hear your experience/how your are caring for the dress. Thanks! -Emily Also! Just a little note about two changes I made that were quite successful, if you're interested.... (1) Instead of using a back facing (I typically dislike "loose" hanging facings), I ignored that pattern piece and just cut two back bodices, one from my main fabric, and one from a lining fabric. It worked like a charm and the back is essentially lined. (I fully underlined both my dresses, so this method worked well with the overall construction of the dresses.) The back looks nice and clean on the inside! (2) On the second Garden Party dress I made, I reversed the order of the construction of the front yoke. I didn't love, the first time around, having to edgestitch to attach/finish the yoke on the front side of the garment, so I attached the yoke front directly to the dress front, right-sides together. In other words, instead of the yoke front folding down and finishing on the FRONT, I flipped the process, so it was the yoke FACING that folded down and was finished on the INSIDE. I still did my edge-stitching from the front side (catching the yoke facing in the process), but it just looked much neater and I had no problems! The dress turns out great either way, but I liked the perfection of the stitches by doing it this way the second time around. Just thought I'd share that! Thanks for any feedback about washing!
