Why missing features when buying cloth's

[dogb8t]

Why are there missing features when buying cloth's. 

I'm trying to by underwear for my girlfriend and there is no option for sizes !

She is a size 4AU to 6AU but there is no option to search any sizes !

I'm starting to dislike ebay, I think I'll start looking elseware to buy stuff because the changes getting removed from ebay SUCK !

I just tried the same search, and there are sizes on the left, but not very accurate.

Some sellers do add dimensions, but not all, and sizes like  S,  M etc. can be quite deceptive.
