ASOS blush pink long-sleeve stretch button-up

I wore this to a wedding. I looked hot. I'm not going to wear it again. It definitely fit me; it's an XL and it measures for a 46 size chest. It's definitely a slim fit with a little stretch. It definitely turned out to be a darker blush than I thought so pay attention to the hue of my pictures vs the professional ASOS pictures. Okay buy my shirt and have yourself a hot girl summer! Also it's 97% cotton and 3% elastane! What does that mean? Buy it and find out!
