size 5 to 6
22 uk, 2x u.S
In the UK a size 10 dress or skirt has a 28 inch waist and sizes go up in increments of 2". Size 12 would therefore have a 30" waist, size 14, a 32" inch waist, size 16, a 34" waist, size 18, a 36" waist and so on. For a waist 33" you would either have to settle for a size 14, with a 32 inch waist, or go one larger and get a size 16, which would have a 34" waist.
a 23-inch waist is size 0 in the uk and in the us its a 4 though this will differ on different brands of clothes slightly
Probably a US size 6 (which is UK size 8 I think...)
big
8 :)
You need to be more specific.. Where is the dress from? Is it a US size 26 or an Australian 26 etc Im Australian, so with the research that I just did on the internet a dress size 26 is on average a waist size of about 45" (inches) Which is considered to be a plus size, if you're not talking plus sizes please let us know. The inch size for a dress size 26 varied from site to site but on average it was between a 44" to a 47" I guess it depends on the dress itself. Hope I was of some help =)
