Speaking of sheer fabric, let's hang out in 1830 today. The 1830s are one of my favorite decades for the absolute bonkers direction things went in. Skirt hems went up, waistlines dropped, crinolines puffed, sleeves swelled, and hair went miles high with every kind of adornment you could imagine. For a truly exciting experience, search for hairstyles of the period and you'll see that the whimsical designs in Bridgerton weren't far off from the truth (just in the wrong decade).
This delightful dress employs aerophane in the construction of the flowers. Aerophane is unusual sheer, made of silk, and was only used until around the 1870s--but it had a lot of ideal qualities for the time. First, it had a beautiful shimmer, which caught the light of ballrooms for lovely effect. Secondly, it was ideal for embroidering and shaping, as it had an elasticity other sheers and nets did not have. Lastly, it held shapes, pleats, twists, and rosettes very well, so you could achieve remarkably artistic whimsy in borders and embellishments.
Here, the silhouette is absolutely darling. The pleats at the top of the bodice and that swooping neck hearken to the next two decades of peak Young Victoria.
