More feminine, no. More attractive, yes.
If you want to have a convincingly female presentation, every little bit helps. There are a lot of women with varying amounts of upper lip hair too! That's not a reason to skip shaving well and using foundation.
Also, men's fat deposits are not typically in the same places as women's (using the terms "men" and "women" here to refer to XY and XX people). Male fat tends to go to the gut, female fat to the thighs and so forth. For this reason alone, an XY who has the same proportion of body fat as an XX won't look the same, and the clothing won't fit the same.
If you like your weight, you're fine -- you don't need me or anyone else to convince you otherwise. But a "feminine shape" has certain proportions of bust to waist to hips. If you don't believe me, look at a few women's clothing sizing charts. My body shape is not on any of them, I can tell you that! If you've got a gut, you'll have to build an awful lot of bust to make your waist look proportional, and then you're going to look like a tank truck.
That's my opinion, anyway. And I'd rather not look like a tank truck.
