Hi Wei - thanks so much for your interest in Gwynnie Bee! We currently start at a size 10. With summer approaching there will definitely be more sleeveless/shorter styles but you may want to check back in the fall for more modest silhouettes.

If you dug around the site and didn't find like the current offerings, I would think that the service wouldn't be right for you. Really, not all that much is offered in 10 to start with. I use LeTote and they really don't have that many dresses to start with; I don't feel most of them are very modest. However, with GB, I know that I saw some modesty fashion bloggers who would post themselves in GB. Many of them had some very clever modifications for the dresses -- putting a shirt under something sleeveless, etc. I recommend you try searching for some modesty fashion bloggers to see if there are creative ways to make these services more useful!

I tend to wear similar things, and I've been a happy customer for years. I am larger, though, so the 8-10 may not be available in all their offerings

GB does have clothing in size 10s so you can try that. That might work especially if you want to wear things on the looser rather than tighter end. Also, there are other services like Le Tote and Stitch Fix that you might be interested in looking at as they are closer to your size range. For short sleeve tops and dresses, I frequently pair them with a basic black or navy cardigan and dark tights for work.

Try Letote.com. They have a lot of very modest dresses.

I haven't seen any rental sites for more modest clothing but there are plenty of online stores that sell dresses, etc.
