plus-size corporate steampunk at Roaman's, of all places
Being a plus-size gal, I have long relied upon Roaman's for bras and bathing suits to accomodate my double Ds. But I've always considered their clothing to be mostly cheap and garish - specializing in oversized mumus printed with brightly-colored tropical flowers and that sort of thing. Their latest catalog has made me change my mind. It's like an entirely different company took over. Not only are there plenty of items that would be acceptable for the office, there's quite a lot that's downright cute and dare I say, steamy? I think their buyer must have gotten a whiff of steampunk somewhere. They even have a page set aside for "military chic" (I am not linking to it because the stuff on that page is not particularly military in style, with few exceptions). Many items would work well for the office and possibly even for your steampunk costumes. Note that their sizes tend to run large and many things are tent-like unless it specifically says "princess seams" or something along those lines. If you are patient, many of these things will eventually be marked down, or you can find a coupon code for 40% off, free shipping, buy one, get one half-off, and that sort of thing.
Sorry I don't have time to do the thumbnails but here's a sampling of their more steam-able offerings:
Gorgeous Ruffle Shirt that I adore - love the sleeves, and can tolerate the elasticized waist if I cover it with a belt
Military Jacket 1 - Napoleonic style
Military Jacket 2 - reviewed in detail on the Plus-Size Steampunk community (it's warmer than it looks)
Military Jacket 3 - love the mandarin collar and antiqued buttons
Ruffle Blouse - not military, as described, but could work for a variety of steampunk styles
Military Skirt - not sure why they consider this military but it reminds me of The Prisoner and there's something vaguely steamy about it
Ruffly blouse - for an Edwardian Tea Party
Extra pouf-y sleeved shirt - Lolita-ish
Serviceable Victorian-ish blouse I could make do with this
Ascot Vest - are you supposed to wear this with an ascot tie?
Pinstripe vest - nice full coverage for women of ample bosoms
Western denim vest - flattering for cowgirls and other Americans
Western style bib front shirt - reminscent of the frontier-style men's shirts
Low-slung belt - consumer reviews say this runs large
