Since I get warm very easily during the summer months I wanted a loose-fitting, cool top to wear both at home and out. The material's a loose cotton which is very comfy, and general style is very loose and nice. The arm holes are low and baggy and the whole top is generally lovely and comfy.
Normally I fit a size 8/10 top but got the large (12/14) for the extra looseness. These tops are smaller than advertised, though. They're not snug on me, but they're definitely not a 12/14 size. If you're my size get the large, but if you're over a size 16 or so I doubt the large would fit comfortably.
The material is thin enough to see through the white one fairly easily, so if you're bothered about people seeing underwear I recommend skin-coloured or white underneath the white top, and don't wear it if you're planning to get drenched!
Good shirts, arrived quickly, good value for money, would recommend.
