How about something like this ? This one in particular was quite see through when I tried it on, but there are many similar options if you search one shoulder accordion dress. I love how it flows! More on reddit.com

I think the cut, colour, and print on the first one don’t read as formal (gorgeous summer dress though). I think sweat will be very apparent on the light coloured silk slip dresses (I, for one, sweat like mad at destination weddings) but they’re beautiful. Silk is amazingly light and breathable in hot weather. Excellent fabric for a beach wedding IMO but perhaps a different style or colour, and / or shape wear underneath to absorb the sweat and smooth everything out? ETA: more than one layer of silk will be better for not showing sweat. Patterns/printed fabrics and darker colours also disguise sweat. A slit helps avoid overheating when wearing longer dresses / gowns. Polyester is likely to be the hottest and most uncomfortable fabric you could potentially choose to wear. Silk can be expensive, and buying secondhand from sites like Poshmark really helps keep costs down (consignment stores can also be great but perhaps hard to come by in smaller towns) if that’s a priority. I’m personally quite partial to Reformation’s dresses, and think the silk ones are stunning. More on reddit.com

Oh, beach weddings are fun, but finding the right dress can be a bit of a hassle. Have you tried checking out ASOS? They usually have a wide range of options that might be perfect for a beach setting and their prices are usually pretty reasonable. Another place might be Nordstrom Rack if you're looking for quality without the steep price. And if you're okay with pre-loved options, Poshmark could be a gold mine. You can find some nice stuff there that's barely been worn, which is good for your wallet and the planet! Just make sure to read the return policies wherever you shop to avoid any oops moments.
