i would say a week's worth. you could get by with less, but why do that?

DD graduating this year. She has had the same two awful polyester skirts for 3 years (bought used). Shirts, 3 navy polos, 2 white (which she never wears). A couple of sweatshirts.

Don't over do it - you can always buy more, you can't return the used stuff.

DEFINITELY buy used if you can - there is no need to buy new, especially if young and still growing

I buy a week’s worth and ensure those clothes get washed every weekend.

Depends on how often you want to do laundry. 🙃
One full week’s worth works for us. Also depends on the age, when they’re younger they usually need fresh pants every day, once they’re older they can wear again.

Most schools have uniform exchanges or sales. Go there and get as much stuff as you can. Then supplement.

Used skirts/jumpers are the way to go. They are indestructible; there will be landfills of polyester plaid skirts decades from now.

I try to have a week’s worth of both warm and cold weather pieces— so, 5 short sleeve and 5 long sleeve polos, 5 shorts, 5 pants, and for my daughter 5 skirts/jumpers. Our school has one formal day per week, so I have one slept sleeve/one long sleeve formal top.

Extra ties and belts are good to have on hand because boys especially lose them or ruin them in bizarre ways.

I honestly see no cons to getting secondhand items from other families at school. Kids grow so fast and it’s great to have backups. Our school does a uniform swap twice a year, and also keeps a closet that parents can check year-round to drop off outgrown items or pick up new ones.

For a boy, I've gotten away with 2-3 navy slacks (or 2 shorts for fall/spring) and 3-5 shirts. he wears the bottoms twice before washing but he wears a clean shirt daily (because he's slobby and stains the shirts often). One PE set for winter and another for fall/spring.

But I have to do laundry midweek.

Find out if your school has used uniform sales.

How old is your child?
My daughter has 3 fall skirts / 3 winter skirts
5 fall tops and 5 winter tops

She comes home from school and hangs up her uniform skirt and puts her top in a designated wash bag. Her uniforms are washed by themselves in delicate cycle in woolite in order to extend the life.

My kid has 2 short sleeve shirts 2 long sleeve shirts and the PE uniform she wears once a week. That has been enough for us, she wears a shirt for one or two days. I buy those new because they have to have the school logo.
I but khaki pants and shorts from the thrift store. I have found Lands End, Gap, etc there for $4-6 in great condition.

How often are you doing laundry? I go with 5, but I probably could do 4 since I do wash on Wednesday and Sunday.

Five full uniforms. Two special occasion blazers, used.

The answer to this really depends on how often you do laundry. Gently used uniforms from the school are great, but admittedly I have never done that.

If a boy buy used whenever possible and get more than a week. They will lose uniform clothes in ways you never thought possible.

DC starting private this fall. I know they need the required blazer for special occasions but how many complete uniforms should I buy? How much is enough? A week’s worth? Two weeks? Also, what pros and cons of buying used / gently used uniforms from the school?
