It is too small, but I am making it work.  I ordered a L (just in case).  It fits like a small.  When ordering, go up 2 sizes than your normal shirt size.

However, it really makes you sweat!  I love it and would order another one...2 sizes larger.

It's about 3 sizes too small. I bought an 3x and it is almost too small on me ( I am a large)

I bought the item two sizes bigger and it was still snug.  It was a gift and I was embarrassed by the way the item fit.

It was a disappointment. Ithe sizing runs Too small.  Even though I ordered a size larger than I normally wear. I recommend that if you order this item, go 2 sizes up to make sure it will fit.

My daughter is 18 months old and wears a size 3. I ordered a size 4 to be safe and she can't even squeeze into it. It looks like a size 2 at best. It's cute but what a waste.

I bought a 3x and my daughter who wears a medium adult can wear it. I would NOT recommend this.

Fits two sizes too small. I would need to lose 20 lbs to wear them. If I had known, I would of ordered 2 sizes bigger. They seem to be made for women with exceptionally small frames. And I'm considered small.

Way too small, like two sizes too small.  Had to return it.

I'd totally give it 2 and a half Stars. The skirt fits perfectly the shirt seems to be two sizes too small. the shirt doesn't match to the list of measurement on the size chart. I like the skirt though!

I really like the style of the shirt. However, it was two sizes small. It fits like a M (U.S.).

Two sizes too small fit-wise. The neck is too small and the example pictures are deceiving. The color is good though - such a shame I can't wear it the way I planned to.

I like the color and material, but it's too small to wear. This is NOT a one size fits all.

The robe itself is very nice.  The problem is it runs about two sizes too small.

For some reason you have to order 2 sizes bigger than you would normally order, they  are made to fit a A mannequin.

I ordered a 3XL so I could at least be sure it fit.  If anything it should have been WAY too big for me.  I wear an XL, so I thought if I went that route I'd have a little room to spare, and if the cut was a tight as I suspected, it wouldn't be a problem.  Sadly this thing barely zipped up on my 90 pound 13 year old son.  Maybe I need to lose some weight anyway, but good lord, when you order 2 sizes too large and it's still too small then maybe your size charts are a bit off.  Just saying.  It did look good though.  So credit where it's due on how well put together it is.  But unless you're a small person, don't even both.

I have worn the bra twice and each time it has been soooo tight.  I think the size is 2 time 2 small.
