To be a V shape, your shoulders need to be wider than your hips, by a good couple of inches. You may or may not have a waist, many V shapes have a shorter waist, if so, then use the tips from the H shape through your waist area – that is – no tucking, detail, pockets, belts, gathering, pleats etc. at the waist, so as not to draw attention to your lack of waist.
Look for raglan sleeves, halter necks, dolman sleeves, kimono sleeves, which will visually narrow your shoulders. Flared or wider cuffs will also balance your figure, as will hems that end around your hips.
Narrow lapels or no lapels are best on jackets.
