When you say you "glammed it up", that could be your cue to what happened. I have a number of observations on this, having lived through it myself.
The first is, too often, transgenders over-dress or portray themselves with a slutty look. You don't put on super long false eyelashes and glitter your hair to go grocery shopping.

The second is that transgenders also dress in a manner that stands out. If all other natal women will be likely to be wearing jeans and a top, it's unwise to wear a sequined slinky dress and 5-inch heels.
Finally, acting nervous will make you stand out. Looking at people to see if they're looking at you can cause them to look at you.... I sometimes attend live support group meetings and there is one poor girl who is so self-conscious that her eyes are constantly going all over and she just stands out because of it.
So, go to the mall, get a drink at the food court and spend some time watching other women. See how they're dressed, how they walk, how they stand and what they do. Then, do your best to dress in a manner to fit in with those who are your age. Mature, middle aged women don't dress the same way as the 15-year-old girls.
For my first real attempt to go out in the world in preparation for full time, I called a nice department store, informed them that I had been clinically diagnosed as being transgender and was transitioning under medical supervision and wished to get some help buying some nice outfits. If they weren't comfortable with that, please let me know and I'd go to a different store. They said they would welcome me and I got a name to contact and a time to arrive. This was a stretch, because I hadn't started therapy yet, but I'd made up my mind to transition.
She helped me choose slacks, a top, a purse, a necklace, bracelet and ear rings that all went together and I looked superb. I never got a second look when wearing those clothes. I HAD gotten a lot of second looks before, just like you believe you had.
Change your approach and I believe the results will change. Don't give up, you can be accepted. I've been full time over a year now. It's wonderful.
