The easiest fix? Take in the sides! I flipped it inside out and pinned up the sides.
And then I chopped off the extra fabric.
Yeah, it just that easy!
Wanna see it again? OK, sure. Take one too-big shirt...
Flip it inside out and sew up the sides and sleeves, if applicable...
Trim the excess (you'll also note that, whenever possible, I salvage and reattach the laundering tag, just in case).
And you're done!
I did this to several more tees on that therapeutic Saturday, but seeing as how all the before and afters would be essentially the same, I won't bore you. Suffice to say, I regained a good chunk of last summer's wardrobe in the span of a few hours.
