Morning ladies!
I've been following your talk although busy with the other thread so it seems that both of the threads are doing well. Win-win? 
And loving the vibe here too!
QC your dress (Davina no?) is a classic and will not date quickly. In my opinion, every woman needs a slightly more formal dress for things like cocktail parties, imprompu invitations, family celebrations, visiting elderly relatives, going to good restaurants etc. It's okay if you only use it a few times each year. Today is Mother's Day, wear it for lunch and have some family photos taken?
I know I'm much more formal/classic than many of you but I wear dresses like that all the time. When it's warm I wear them with bare legs, flat shoes (this summer's pointy toe or kitten heel look in a contrasting color - yellow, emerald green? Or the demure nude or maybe a sling-back or an espadrille), and a chunky bracelet (to give it some edge, think about budget versions of the classic Hermes collier de chien bracelet). And a tiny bag if going out. The dress has a lovely silhouette and hiding it with a cardigan/ jacket is a shame, but of course you can do that too.
I also try to create opportunities for myself to wear the nicer stuff (going to gallery openings, cocktails at home etc) to offset the monotone of SAHM/working from home life. In fact just about to do an hypermarket run from hell because we are arranging a big party at home later this week and need to get the drinks etc (dinner parties too fraught - cocktails much easier, and friends like them too because they can go home early and it's not such a commitment). And going to a party in a boutique tonight. (Not a shopping party thank god - my sideline in perfumes has occasional nice perks )
Lots of ladies here have the Davina. How do you style yours?
