uniqlo size help

[whiskersonkittens80]

Hi I'm looking at uniqlo easy care shirts and needing some help with sizing please?

I'm a size 18/20, 38D bust, 5'5 height. Would XL be a good size or would it be too small?

I don't want to be ordering anything then find I have to send them back. There isn't a store near me.

I'm getting some shirts for work.

My MIL and I bought Uniqlo's ultralight down jackets recently and found their sizing very small.

I am an 8/10 and usually wear a Small size, but the Uniqlo Small was definitely too tight. Have exchanged it for a Medium which is great - good size, not baggy.

MIL bought a Large (she is a 14/16 but likes her jackets to be loose fitting) and found it too snug for her liking.

On that basis I would definitely go a size up from what you would normally go for.
