I've spent half the morning searching for a dress that does not appear to exist so I'm reaching out in the hope that someone, anyone may have some useful links for me!
Requirments, sleeveless (but enough to hide bra straps!) and casual.
Knee length ish? I fall over Maxi dresses. 
Fits a size 18-20 without making me look like I'm trying to cover up or squeeze into a sausage skin.
My body shape is a lanky 🍎, best way I can describe it.
42H boobs means I cannot do without a decent bra, I'm also tall 5'9 so don't tend to wear anything other than trainers or flats on my feet!
Budget of £40 -£50 maximum
All links welcome.
