/cgl/ - Cosplay & EGL

So I'm making a coord with the mermaid princess skirt I have. It's not a finished collage yet but I'd like some direction on what pieces I should look for. I'll be on the search for a pink blouse with short sleeves for my first coord with this skirt (I really like the wristcuffs with the seashells to not go ahead with this).

About the rest of the accessories though, which should I use or which should I not bother buying? For the shell hairclip, pink would work best right? At the bottom right, there's a crown I played around with and added pearls. Should I try using it for a more OTT coord or nah?

The two shoes at the bottom are in my wardrobe already. Which works best? (Sorry I'm not interested in buying new ones unless absolutely necessary).

And lastly, I'm stuck on legwear. I can use basic lace white tights with the coord, and I haven't found any other interesting legwear I could use, so I decided to try getting the matching OTKs. Should I get pink or offwhite? I'm not sure on either because the pinks look bright compared to the dusty pink of the skirt, but the offwhite may look off/be too creamy.

Sorry for all of this, I'm an indecisive person and I'd appreciate any input. Once I have a color scheme/direction to go in, I think I can work towards finishing this coord. Thank you again for any help I receive!
