In short; I'm 40 & want a killer dress for my party in June that makes me feel fab. I've been looking online for months & even at previous MN posts on this subject, can't find anything I like or is appropriate (I generally struggle with clothes shopping... don't have the stamina). PLEASE TAKE PITY ON ME AND HELP!
I am a size 12/14, big boobs, hourglass, solid bum/thighs/legs... the internets and Gok Wan inform me that I need a v neck, midi/knee length dress. Ideally one that covers my arms or with at least has some sort of sleeve as my arms are on the chunky side. Party is in June, indoors so I'm thinking knee length.
Would be forever grateful for any inspiration... or should I take myself for a style consultation at a department store? Are they any good?
Please help a style numpty!
