NabtosCotton String Bikini Hi Cut Women Underwear Checky Multicolor Black Panties Pack 6, Multicolor, XL

Q: Can you only buy these in a 3 pack or will i get all the panties shown at the top for multi colored 1?

They arrived in a multipack with all different colors.

Q: What's the hip measurement on these? If they arelow rise, why are they sized by waist?

Most clothing is listed with a waist measurement, even if the clothes don't actually sit at the waist; I don't know why. Asked the same thing before; no answers. But here's an average size chart for underwear if it helps at all. This particular brand is pretty average in size, so just order what size you normally wear. 5/S: 36"-38" hip 6/M: 38"-39" hip 7/L: 40"-41" hip 8/XL: 42"-43" hip

Q: I am 5'4" and 115. what size should i get?

I am full figured/curvy and I had to go up a size for better fit. You seem to be petite. I would say go with your regular size. I truly adore these in certain colors. I've had about 2 light pink pair that fitted smaller than the blue, white, hot pink, and purple stripe. Overall, I love them. I hope this helps.
