I found a great Diane von Furstenberg maxi on the Outnet for a recent wedding. Bright, lovely pattern and incredibly comfortable. I'm in my 60s and there was nothing matronly or MOB about it. Good luck. More on reddit.com

I am in the US, and I just ordered 4 from ASOS to try on! Do you have any specific styles in mind? If we ordered any of the same, I’m happy to share some of my photos, and specific fit details if you’re interested! Here are 3 I tried (the other one is now discontinued.) dress 1 dress 2 dress 3 The dresses were shipped in garment bags inside of large boxes, so they were well protected. I found the materials to be good quality. I didn’t order any styles that were particularly tight on the lower half so I didn’t notice any issue with them being see through. The issue I had was that, using their “fit assistant,” it suggested I would fit in a size 8 or 10, and when I tried on the 8’s I ordered, they were too big. That might be a me problem, or you might want to consider ordering a size down as well just to check fit. I returned all 4 today, they are en route to ASOS, but it was easy to request a return and print the prepaid labels. YMMV in Canada. More on reddit.com

I ordered two of these for my bridesmaids. https://www.asos.com/au/maya/maya-bridesmaid-sleeveless-midaxi-tulle-dress-with-tonal-delicate-sequin-overlay-in-navy/prd/24035662?colourwayid=60533678&cid=15156 I got them on sale, and with a new user discount code! They arrived quickly (I think they shipped from the UK). I only had two issues... Loose stitching at the top of the strap on one (easily fixed at home) Some of the sequins came on (again an easy fix at home) Otherwise the dresses were close to measurements and fit really well. I didn't want to spend much on a wedding dress either and ended up ordering from White Runway https://whiterunway.com.au/ as I could try everything on in their Sydney showroom. I ended up spending around $700 including 2 lots of alterations as I had to postpone by a year. More on reddit.com

Honestly, the number of times i dont think of macys first then get last minute guest dress for reasonable prices there is wild. If you're US based. I've done well at tj maxx and marshalls. Though that can be area dependent. Otherwise lulus, nordstrom, Karen millen ((though a bit more expensive on the expensive) hello molly, asos, oh polly, abercrombie is a good option, sometimes you can get lucky on revolve- they have some good options under $200 but def on the trendier side I'll try and think of more places. But I'd start with macys, abercrombie, lulus and nordstrom More on reddit.com
