Do you have a black eyelet dress?
Like, say, this one, from Holly at ?
I don't set myself up to be a "dictator of taste", and I don't think I've ever done one of those "Ten Items Every Woman Must Own" lists, but if I did, a black eyelet dress would be on the list. ("Trench coat" would not be on the list. Has there ever been a fashmag printed that didn't tell you to run out and buy a trench coat? "Trench coat" is like the "free square" in Bingo.)
This is why you need a black eyelet dress: they're perfect. (Okay, okay, I'll elaborate.) Black eyelet has a natural tension between sweet and sultry, between looking (and staying) cool and looking hot. It's easy to dress up or down, and easier still to accessorize. (Black pique is *almost* as good, it's just slightly more casual.)
I've seen black eyelet like this (elegant, restrained) and black eyelet wild (in some 1980s fashion spread — I wish I'd kept it — a black eyelet A-line dress with eyepopping neon bra & briefs under it, possibly a swimsuit, but hey, it was the 1980s, everything was neon).
I've got one black eyelet dress that I've worn nearly to rags, so I'm definitely planning a black broderie anglaise dress for this summer, lined in black batiste (or unlined, if I choose to go the neon underthings route … UNLIKELY).
This one is 38/28/40, and trust me, you will wear it until it gets rusty and falls off you.
