Main Terminal post-security, Island Fashions is the quick last-minute clothing stop.
This small shop sits airside in the Main Terminal at Antonio B. Won Pat International Airport (GUM), on the departures level after security, so you can duck in on the way to your gate without backtracking. It focuses on resort-style casual wear and Guam-branded apparel rather than high-end labels, so think T-shirts, cover-ups, and beach-ready outfits instead of business suits.
Island Fashions usually opens in line with international departure banks, roughly 2–3 hours before major flights, so evening and late-night departures see it most active. Pricing runs higher than downtown Guam shops: expect around $25–$35 for logo T-shirts and $40–$60 for dresses or aloha-style shirts, reflecting typical airport markups. If you forgot light clothing for Guam’s humidity, this is one of the few options past security.
Stock leans heavily on Guam-branded shirts, simple dresses, flip-flops, and sun hats, with a smaller rack of kids’ sizes. You won’t find formalwear or full outdoor gear, but you can piece together a beach outfit or grab a clean shirt before a 7–8 hour transpacific flight. Quality is mixed mid-range tourist-shop level, fine for casual wear but not designer-tier.
Lines rarely get long, but with only one or two cashiers on duty, paying can still take 5–10 minutes right before large departures. Try to stop in right after you clear security, not during the final boarding calls, so you have time to check sizes and compare prices calmly.
