how would clip hair extensions look with long hair?

my hair is already kinda long and i usually onlt see people with short hair use extensions but i want my hair longer. and my hair is realllllly thick. so will it look weird with extensions? and my hair is bleach blonde on top and brown on bottom. what color would i get if i got them?

Funny you ask. My hair is pretty long and I went and bought 20 inches, which was all they had from Sally. Wanting my hair to be longer and thicker. But anyway – they were the same length, but just made hair look thicker, which was cool. But I wish I didn’t buy them, a waste of money. To each their own though, good luck!
