The J-frame or maybe a Kahr P series are also worth trying. There is also the belly band & ankle holster to consider if you are holding fast and resisting any wardrobe changes.Not knowing your body size, maybe you could go with a Tall shirt to cover the OWB holster, or one size larger may do it. Clothes are all cut a little different, so you would have to try them & see.
You could try a Bahrami hip grip on the J-frame also.
