The sheer dress trend definitely requires delicate execution because of its potential to be misconstrued. With that said, there is no real reason to shy away from sheerness provided that you keep just a few things in mind. When styling sheer dresses consider the following:
1) Being that your undergarments are partially visible they need to be treated as regular clothes. What I mean is that they should be paid particular attention. The bra and undies should be opaque, matching, and solid-colored (it’s probably safer to avoid prints of any kind).
2) The undergarments should be full coverage, preferably with the panties being high waisted.
3) Unless you are styling a sheer beach dress over a bikini, the rest of the look should be styled with as much attention to the accessories as usual. Belts and statement jewelry help associate the outfit with evening or daytime attire, depending on the occasion. These cues will contextualize and complete the outfit. Just remember to commit to one theme and go for it!
