It's the perfect lightweight blouse, it has a lovely boat neck all in one sleeve, with a hemmed edge to them.
The body of the blouse is all in one, and it got that easy square thru the body shape that's so easy to fit.
The lower hem edge has a detail row of ladder lace - (known in real terms as faggeting) so not a lacey lace- a detail piping ladder, it adds detail to the style and some fun.
The fabric print does all the work on this easy go to 100% cotton blouse.
I would say it's a generous size so for more fitted go a size smaller. for the looser look stay at your number.
