I gotta agree with Isabel and with Angie. A lot of it, as many of you have pointed out, is just the 'system'. In 18882, the ideal shape was very voluptuous and the vast majority of clothing was made to order or homemade, so no matter your figure - big or small, 'regular' or more off beat, you could get a decent fit in your clothing. And you could have it made up in colors and style lines which flattered you, even if you couldn't afford the most sumptuous of materials and lots of frills.
Falling into the 'smaller sizes' is not a cure-all, believe me. I usually can get into the smaller sizes offered, but do they fit? Ha!!! My body proportions are WAY off of the ones developed by manufacturers. Now, we all know that sizes are all over the place in clothing. However, in one standardized line my sizes might go something like: 8 hips, 10 waist, 14 bust, 18-20 in the shoulders. It's not even like i'm one size up top and another on the bottom! The only dress which fit me gorgeously right off the hanger was my mother's wedding dress, made for her by my Grandma Gigi. But in RTW, anything that fits the hips can't be zipped up past the bust, anything that fits the shoulders is like a tent.
This is one of the reasons i sew. It's also made a huge influence on my style, as i've gravitated towards slouchy and oversized fit as a style statement and also because i dont' want to run around naked The popularity of stretch materials, knit as well as woven, has made a monumental difference in my ability to find things that i can wear - though it's kind of bunk, relying on the stretch for fit.
If i wanted to dress like Angie, with her impeccable fit and tailored elements, i'd spend all my time in the fitting room! And individual garments can only be altered so much before they turn into a hot mess.
Shannon, to your original point i remember reading Kendall Farr's The Pocket Stylist (which i won in a YLF contest, yay Angie and Inge!!!). Ms. Farr was hired by Revlon to style Emme, a plus sized model, for an ad campaign. Long story short, Ms. Farr could find bumpkiss in terms of stylish, fashionable, chic, flattering plus wear for Emme and ended up having an entire wardrobe made for Emme at at tailor's. Now, having things made to order sounds a LOT more trouble than it actually is, the web has made this phenomenally easier. Considering the time and hassle some of us have finding clothes in RTW, it's worth it.
Really, it boggles my mind how much this type of idiocy still occurs - weren't we all supposed to be able to buy unique, computer-fit ensembles by now? so much for the future!!! have fun everybody, steph
