Fgs this always happens with Mumsnet threads. A lot of mumsnetters for some bizarre reason think it’s not ok if a dress is predominantly white even when it is patterned and clearly not a wedding dress.
Hobbs is a pretty conservative brand and this is being marketed as a wedding outfit. I think they know the market better than people not in the business.
It’s fine. You’re going to a formal wedding. The bride will not be upstaged in that dress.
