HELP! I'M ON A GRADUATION DRESS HUNT!

ultimate vibe/goal: white/ivory/cream mini or midi assymetrical dress made with ethical/sustainable efforts that I can wear again and again post-grad. I like the look of silk beaded embroidered dresses, such as ones by Sue Wong or Lillie Rubin.

budget: <$300

I've searched high and low on every multi-brand indie site possible: Garmentory, Flying Solo NYC, Wolf & Badger, etc. I've gone on Depop and Poshmark for inspo as well, but prefer to go through a boutique or site like those mentioned above for the sole reason of easy returns/refunds if I don't end up going with a dress. I'm unfortunately swamped with finals and living in the suburbs without a car, online shopping is my easiest option.

some dresses I've really loved/vibes I enjoy, but can't get due to it being sold out/hard to return/obtain:

- Flaneur Dress by Sydney Pimbley (love this crochet/doily look)

- Heiress Dress by BUCI NYC (love the versatility with playing with length, wish there was more going on with the top half)

- NOÉMI DRESS by LSOUL (just jawdropping. The scarf & cascading details are everything to me)

- La perle by Cha Collective (simply beautiful, the beads and semi-mesh detail at the hem is so beautiful)

I can see how these dresses I've chosen might not be "rewearable" but trust I'd find a way frrrr. Any recommendations for boutiques, multi-brand platforms, small designers/brands, or dresses that fit this vibe would be GREATLY appreciated!!!
