Near FCO Terminal 3 departures, Calvin Klein Underwear sits right in the main international shopping strip where long-haul passengers linger before passport control. It’s post-security in T3, so you’re safe on time once you’re past checks. Think quick last-minute upgrade to your basics rather than a full fashion stop. Stock skews classic black, white, and nude, with some seasonal colors mixed in.
Price-wise, you’re looking at clear “airport markup”: multipacks and bras often run €5–€15 higher than central Rome stores, but promo tables with 2-for deals can soften the hit. Sizes run from about XS to XL on the rack; larger bands and cup sizes can be patchy, so ask staff to check the stockroom before you give up. Men’s trunks and briefs are the most visible items near the entrance, with women’s styles pushed slightly deeper in.
Expect typical Terminal 3 duty-paid hours, roughly first departures to last evening waves, so the shop is usually open from around 06:00 to 22:00. It works well if your airline uses T3 for Schengen-non‑Schengen connections and you’ve got 20–30 minutes to kill near your gate. Returns later by mail can be awkward across borders, so get sizing right on the spot and keep the receipt.
Quick tip: try things on immediately, then repack your old pieces in the shopping bag and board with the new ones already in use; that keeps your carry-on from swelling beyond what gate agents at FCO T3 like to see.
