Last year I bought some sleeveless Hawaiian shirts size XL. They were a good fit at that time, now I have to make an effort to do the buttons on them. It is likely that fairly soon I will have to wear them unbuttoned. They are otherwise the most comfortable tops that I have; since I bought about them last summer I haven't worn any other tops.
My belly is some kind of a mix now: firm above the navel, softer (with an incipient belly hang) on the lower half. It is round shaped but will be interesting how it will evolve when I gain some more weight.
I can grab some fat on the underside of my belly but not above the navel.
One thing that I am experiencing as my belly gets bigger: I can't bend over or lean forward when I sit down - not without spreading my legs and even then it takes some effort to do that. The pictures show how much I can lean forward when sitting with my legs held together or spread as much as my chair allows it.
I guess everybody else here is experiencing the same, especially with a firm belly like mine.
It's a relatively minor inconvenience but I still want to get bigger.
