Buying bigger size clothes and better size bras abroad

In Asia I used to find it hard to find clothes, underwear and swimsuits to fit larger Western bra sizes and hips. Shops catering for Indians rather than the Chinese are more likely to stock your size. I was surprised that skinny tall model like Americans had the same problem. They found dresses and swimsuits too short in the body. When living or holidaying in Singapore I would have to wait until I got on a trip to Australia or New Zealand and then stock up.
Now Singapore has more large sizes in department stores. Mustaphas always has lots of larger sizes.
the new design of bra sizing by volume in the USA has been in the news June 2013.
1 Like feet of different sizes, some women have breasts of different sizes.
2 I prefer front opening. Leaning against those metal hooks against a wood-back chair or even any chair gives me itching at first and after a few hours terrible pain just on my spinal bones. As for lying down for a nap or sleeping in a bra - same pain.
3 The wide shoulder straps are good - the wider the better.
4 How about some pretty colour  and sexy bows, something which looks good peeping round cleavage, strappy tops and large armholes.
5 A bra and pants set looks neater.
6 Next make swimsuits. Or make a set which doubles as a bikini in summer. Great for travelling light or jumping into the pool from a poolside restaurant.
7 How about colour change straps or ribbon inserts to go with different outfits when travelling.
8 Last forever? I read that bra elastic is designed to last 3 months. The only reason that bras seem to last longer is that you are wear 2.3/4 or more bras and buy twice a year.
