Avoid common shirt mistakes with these essential tips! First, get the right fit—ill-fitting shirts can ruin your silhouette. Next, choose the right collar to complement your face shape and occasion. Check sleeve lengths to avoid bunching or excess skin exposure. Select fabrics suited to the season, like 100% cotton shirts for summer comfort. Lastly, nail your tuck; keep it neat for a professional look or leave it untucked if designed for casual wear. Upgrade your wardrobe with quality pieces, like those from Botticelli, to look polished and feel confident every day!
