/cgl/ - Cosplay & EGL

Okay so I am going to get married soon and was looking at dresses that I wanted to wear as a wedding dress. It's going to be a kind of last minute wedding so I don't have time to get any sort of custom ordered dress or anything. I was looking at this dress (Baby the Star Shine Bright's Innocent Rose JSK) and I was wondering if any of you thought it would look weird if i we're to tack on another layer of ruffles on the bottom or wear an underskirt. I'm 5'4 and the dress length is listed as 93 to 94 cm on the website. When I measured that on myself from the shoulders it came to a little bit above the knees and because of the church setting I'd like to have it at least reach my knees, maybe go a little under them. Thoughts?
