People always say they want to gain fast well it doesn't work that way most of the time.
You have hit a point where your body just doesn't react so let it regulate itself. Just keep eating more and eventually you will see the gains start back up.

My gains over the years went to my butt hips and thighs mostly then after a short period where I lost weight and started gaining again my belly saw enormous gains

Anywhere it wants to LOL

You are so welcome I hope you find some great items

Torrid is pretty cost effective.
I shop Goodwill a lot just because its a great bargain. I hate paying full price for clothes.
Penny's Catherine's,Woman Within or Lane Bryant are good choices.

Muscular with a little extra chub

Congrats.
I always loved finally fitting in the next size up.

OMgosh I would have felt the same way.
I always notice the big guys and I make sure they see me checking them out.
I am so shameful LOL
