How to deal with being compared to sisters?

I have three older sisters and one younger brother. The oldest is 37, second oldest is 30, third oldest is 27, and I’m 22.

For so long, people have always compared us by looks. I think we’re all good-looking and attractive, pretty fit, we take care of ourselves but I’m not really the “high maintenance” type but my sisters kind of are.

Anyways, I hear people constantly talking about our looks comparing who is prettier and who’s least prettiest and it hurts my feelings. Especially old family friends and customers from my family business that ask “Where’s your sister? The pretty one?” or “Where’s your sister the, the prettiest one?” constantly (They’re talking about the 37 year old)

It hurts my feelings to know that they’d say that to my face, not only is that an insult to me but my sisters as well. My sisters get told they’re pretty a lot but my oldest sister is always called “the prettiest”. It’s usually by the older people that are foreign (Asians, Europeans, and Africans)

I’d post pics of us but then it’d seem more shallow and it’s without their permission which is probably bad.

She is standard pretty with a more narrow nose and slimmer face and bigger eyes, I hear from a lot of guys she is pretty but has a mean personality with a “better than you” attitude. But she gets better treatment with crazy stalkers and guys wanting to marry her.

I know she’s prettier than me but I hate when customers/old family friends are rude and say it out loud. How do you deal with that?
