I have ordered two - one in size M and one in size S for two girls.
They have sent me the wrong color so I am sending back.
Beware those little windows that you select color.

One says: as in the picture, another says plain color, another says multicolor.
I have no idea what they mean and I was under the impression that if I older plain one color I will get just blue or just white or what not outfit and not as pictured blue and white righ? because otherwise why to have two options for the same? so I ordered one color plain and I got just as pictured blue and white.

My daughter tried it on to see if she liked it despite it was two colors
so I can tell you what we feel

SEVEN AND A HALF, THIN BUILD - SIZE S FITS:

Size S fits just fine. Perfect in terms that it is not too long, not to baggie not anything. So size S is what you need for 7.5 size of normal height girl and skinni to normal built. I don't know how it would fit for extreme plus size, might be snug but if a child is slightly overweight it should still fit. It is not super snug and it is stretchy so it will adjust somewhat.

Fabric - yes, it is super cheap. Imagine that cheap poliester of a quality just a tad thicker then a ladies underskirt slip, just thicker a bit and so it is not see through. so flimsy, fand it flows on a child.

The white apron is made of the same quality material and so is the hat, they are all the same everythign is made of the same fabric in different colors.

Now, if you are seriously in need of this costume beware - we opened small one only to see the fit and if it will work but even before openning it I saw
the pattern on the front was running those little cross ribbons have little thingies like hoop loopson them and htat part was detached and hanging loose.
I am not sure if it was fixable I am not a seemstrres, but the quality is just bearly there so you might expect some problems that you will need to address, or you might want to order two to make sure you got one perfect and then pay and return the one you don't need if it is defective. As a mom I know how important it is to have a cosutme that is presntable when you need it immedaitely.

LOOKS - it is acceptable, if you expect little from it, maybe few uses.
My daughter and I did NOT like the looks. My daughter did not look like
a historical fiugre or even an average colonial girl, she looked straight
foward like a maid and this was somehow not what we looked for. IT ocmes to your mind immediately and whoever saw this on her and three people in the house who ha dno idea what it was supposed to represent - my mom my dad and my husand said, oh what a cute little maid costume, and they know history.

Yes, the girl looks more of a Cinderella or some Princess' maid then colonial girl. Then again it migt have to do with the fabric quality but also the color is not exactly very complementing the loks and that blue brings cindy to mind.

I am sending them both back because this is not what I ordered, I think that one plian color like blue or whatever would NOT give you that maid look to it.
Then again the price is dirt cheap and IF I wanted this look I suppose the quality is adequate to the price. so it is good deal after all. If you need something for one time and you agree with the look and feel then go for it.
YOu can't make a costume for this price.
