After several frustrating episodes of having skating dresses made in Singapore, I have turned to buying dresses on eBay. There is a lot more variety in styles, and of course there's the thrill of actually winning a bid!
Here are some of the sellers on ebay that I watch. If you readers have any other favorites, do share!
If you still want to get a dress made locally, the only place I would tell anyone to go to is Stage Image. Their products are reasonably priced, and fit comfortably. The only drawback is that the fabric selection is rather limited (but isn't it that way for most places in Singapore?). Also, they often get really busy, so you do have to make sure you place your order well in advance!
I'm sure there are other places, but if you're thinking of suggesting Sonata, please forget it. I have had not one but two horrible episodes with them!
