Shoe Help!

I purchased my dress pre-owned off StillWhite and it's perfect except for the fact that the length is making finding the right height shoes difficult. I bought 2 1/2" heels, 2" heels, and flats with a subtle wedge footbed making them about 1" high and none quite work. I really need a block heel or wedge that is about 1.5" high, but they are super uncommon and the ones I found either don't look bridal or had awful reviews saying they were cheaply made and/or really uncomfortable. I'm willing to get plain ivory, blush, nude, or pale blue shoes and decorate them myself if I can find the right heel height that is comfortable.

The issue I keep running into is that listed heel heights aren't always an exact measurement, and most brands measure just the height of the heel itself and not any additional height provided by the depth of the footbed, unless it happens to have an open back. Also shoes with 1.5" heels tend to have skinny kitten heels and our ceremony is on grass, so I need something bulkier that won't sink into the ground. Ideally I'd love a neutral shoe with either lace or pearl embellishments, nothing shiny or blingy.

Help!
