IDEAS PLEASEEEEE

Ingrid
Im attending a weeding in August and i just bought this dress online from JcPenny AND IM IN LOVE😍 im hoping it fits good, but it should bc i looked at the size chart and everything. but ok i have a couple of questions😊
1. Im going to wear heels for the reception but then i'm planning on changing into cowgirl boots towards the end of the night when my feet start hurting😂😂 i know it's not gonna look the best BUT will it at least look decent with boots? (i've read reviews and seen pictures and the dress appears to be longer so the shoes won't show as much) 
2. im going to get fake nails put on for that day, so what color should they be? and what color should my toes be? i want them to mach the dress. 
3. what kind of jewelry would look good with this?
4. since its summer, i'm planning on getting my hair done in an updo.. are there any good hairstyles for people with SUPER TICK AND LONG HAIR? something that will stay in place for a good while??😅ANYTHING AND EVERYTHING WILL HELP😘
